It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the library's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

These routines operate +on arrays of unsigned 32-bit integers of type ULong, a signed 32-bit +exponent of type Long, and arithmetic characteristics described in +struct FPI; FPI, Long, and ULong are defined in gdtoa.h. File arith.h +is supposed to provide #defines that cause gdtoa.h to define its +types correctly. File arithchk.c is source for a program that +generates a suitable arith.h on all systems where I've been able to +test it. + +The core conversion routines are meant to be called by helper routines +that know details of the particular binary arithmetic of interest and +convert.

On systems where native +arithmetic can easily make one-ulp adjustments on values in the +desired floating-point format, it might be more efficient to use the +native arithmetic. Routine strtodI is a variant of strtoId that +illustrates one way to do this for IEEE binary double-precision +arithmetic -- but whether this is more efficient remains to be seen. + +Functions strtod and strtof have "natural" return types, float and +double -- strtod is specified by the C standard, and strtof appears +in the stdlib.h of some systems, such as (at least some) Linux systems. +The other functions write their results to their final argument(s): +to the final two argument for the strtoI... (interval) functions, +and to the final argument for the others (strtop... and strtor...). +Where possible, these arguments have "natural" return types (double* +or float*), to permit at least some type checking. In reality, they +are viewed as arrays of ULong (or, for the "x" functions, UShort) +values. On systems where long double is the appropriate type, one can +pass long double* final argument(s) to these routines. The int value +that these routines return is the return value from the call they make +on strtodg; see the enum of possible return values in gdtoa.h. + +Source files g_ddfmt.c, misc.c, smisc.c, strtod.c, strtodg.c, and ulp.c +should use true IEEE double arithmetic (not, e.g., double extended), +at least for storing (and viewing the bits of) the variables declared +"double" within them. + +One detail indicated in struct FPI is whether the target binary +arithmetic departs from the IEEE standard by flushing denormalized +numbers to 0. On systems that do this, the helper routines for +conversion to double-double format (when compiled with +Sudden_Underflow #defined) penalize the bottom of the exponent +range so that they return a nonzero result only when the least +significant bit of the less significant member of the pair of +double values returned can be expressed as a normalized double +value. An alternative would be to drop to 53-bit precision near +the bottom of the exponent range. To get correct rounding, this +would (in general) require two calls on strtodg (one specifying +126-bit arithmetic, then, if necessary, one specifying 53-bit +arithmetic). + +By default, the core routine strtodg and strtod set errno to ERANGE +if the result overflows to +Infinity or underflows to 0. Compile +these routines with NO_ERRNO #defined to inhibit errno assignments. + +Routine strtod is based on netlib's "dtoa.c from fp", and +(f = strtod(s,se)) is more efficient for some conversions than, say, +strtord(s,se,1,&f). Parts of strtod require true IEEE double +arithmetic with the default rounding mode (round-to-nearest) and, on +systems with IEEE extended-precision registers, double-precision +(53-bit) rounding precision. If the machine uses (the equivalent of) +Intel 80x87 arithmetic, the call + _control87(PC_53, MCW_PC); +does this with many compilers. Whether this or another call is +appropriate depends on the compiler; for this to work, it may be +necessary to #include "float.h" or another system-dependent header +file. + +Source file strtodnrp.c gives a strtod that does not require 53-bit +rounding precision on systems (such as Intel IA32 systems) that may +suffer double rounding due to use of extended-precision registers. +For some conversions this variant of strtod is less efficient than the +one in strtod.c when the latter is run with 53-bit rounding precision. + +The values that the strto* routines return for NaNs are determined by +gd_qnan.h, which the makefile generates by running the program whose +source is qnan.c. Note that the rules for distinguishing signaling +from quiet NaNs are system-dependent. For cross-compilation, you need +to determine arith.h and gd_qnan.h suitably, e.g., using the +arithmetic of the target machine. + +C99's hexadecimal floating-point constants are recognized by the +strto* routines (but this feature has not yet been heavily tested). +Compiling with NO_HEX_FP #defined disables this feature. + +When compiled with -DINFNAN_CHECK, the strto* routines recognize C99's +NaN and Infinity syntax. Moreover, unless No_Hex_NaN is #defined, the +strto* routines also recognize C99's NaN(...) syntax: they accept +(case insensitively) strings of the form NaN(x), where x is a string +of hexadecimal digits and spaces; if there is only one string of +hexadecimal digits, it is taken for the fraction bits of the resulting +NaN; if there are two or more strings of hexadecimal digits, each +string is assigned to the next available sequence of 32-bit words of +fractions bits (starting with the most significant), right-aligned in +each sequence. + +For binary -> decimal conversions, I've provided just one family +of helper routines: + + g_ffmt + g_dfmt + g_ddfmt + g_xfmt + g_xLfmt + g_Qfmt + +which do a "%g" style conversion either to a specified number of decimal +places (if their ndig argument is positive), or to the shortest +decimal string that rounds to the given binary floating-point value +(if ndig <= 0). They write into a buffer supplied as an argument +and return either a pointer to the end of the string (a null character) +in the buffer, if the buffer was long enough, or 0. Other forms of +conversion are easily done with the help of gdtoa(), such as %e or %f +style and conversions with direction of rounding specified (so that, if +desired, the decimal value is either >= or <= the binary value). +On IEEE-arithmetic systems that provide the C99 fegetround() function, +if compiled with -DHonor_FLT_ROUNDS, these routines honor the current +rounding mode. + +For an example of more general conversions based on dtoa(), see +netlib's "printf.c from ampl/solvers". + +For double-double -> decimal, g_ddfmt() assumes IEEE-like arithmetic +of precision max(126, #bits(input)) bits, where #bits(input) is the +number of mantissa bits needed to represent the sum of the two double +values in the input. + +The makefile creates a library, gdtoa.a. To use the helper +routines, a program only needs to include gdtoa.h. All the +source files for gdtoa.a include a more extensive gdtoaimp.h; +among other things, gdtoaimp.h has #defines that make "internal" +names end in _D2A. To make a "system" library, one could modify +these #defines to make the names start with __. + +Various comments about possible #defines appear in gdtoaimp.h, +but for most purposes, arith.h should set suitable #defines. + +Systems with preemptive scheduling of multiple threads require some +manual intervention. On such systems, it's necessary to compile +dmisc.c, dtoa.c gdota.c, and misc.c with MULTIPLE_THREADS #defined, +and to provide (or suitably #define) two locks, acquired by +ACQUIRE_DTOA_LOCK(n) and freed by FREE_DTOA_LOCK(n) for n = 0 or 1. +(The second lock, accessed in pow5mult, ensures lazy evaluation of +only one copy of high powers of 5; omitting this lock would introduce +a small probability of wasting memory, but would otherwise be harmless.) +Routines that call dtoa or gdtoa directly must also invoke freedtoa(s) +to free the value s returned by dtoa or gdtoa. It's OK to do so whether +or not MULTIPLE_THREADS is #defined, and the helper g_*fmt routines +listed above all do this indirectly (in gfmt_D2A(), which they all call). + +By default, there is a private pool of memory of length 2000 bytes +for intermediate quantities, and MALLOC (see gdtoaimp.h) is called only +if the private pool does not suffice. 2000 is large enough that MALLOC +is called only under very unusual circumstances (decimal -> binary +conversion of very long strings) for conversions to and from double +precision. For systems with preemptively scheduled multiple threads +or for conversions to extended or quad, it may be appropriate to +#define PRIVATE_MEM nnnn, where nnnn is a suitable value > 2000. +For extended and quad precisions, -DPRIVATE_MEM=20000 is probably +plenty even for many digits at the ends of the exponent range. +Use of the private pool avoids some overhead. + +Directory test provides some test routines. See its README. +I've also tested this stuff (except double double conversions) +with Vern Paxson's testbase program: see + + V. Paxson and W.

Both gdtoa and strtodg operate on a bits array +described by FPI *fpi. The bits array is of type ULong, a 32-bit +unsigned integer type. Floating-point numbers have fpi->nbits bits, +with the least significant 32 bits in bits[0], the next 32 bits in +bits[1], etc. These numbers are regarded as integers multiplied by +2^e (i.e., 2 to the power of the exponent e), where e is the second +argument (be) to gdtoa and is stored in *exp by strtodg. The minimum +and maximum exponent values fpi->emin and fpi->emax for normalized +floating-point numbers reflect this arrangement. For example, the +P754 standard for binary IEEE arithmetic specifies doubles as having +53 bits, with normalized values of the form 1.xxxxx... times 2^(b-1023), +with 52 bits (the x's) and the biased exponent b represented explicitly; +b is an unsigned integer in the range 1 <= b <= 2046 for normalized +finite doubles, b = 0 for denormals, and b = 2047 for Infinities and NaNs. +To turn an IEEE double into the representation used by strtodg and gdtoa, +we multiply 1.xxxx... by 2^52 (to make it an integer) and reduce the +exponent e = (b-1023) by 52: + + fpi->emin = 1 - 1023 - 52 + fpi->emax = 1046 - 1023 - 52 + +In various wrappers for IEEE double, we actually write -53 + 1 rather +than -52, to emphasize that there are 53 bits including one implicit bit. +Field fpi->rounding indicates the desired rounding direction, with +possible values + FPI_Round_zero = toward 0, + FPI_Round_near = unbiased rounding -- the IEEE default, + FPI_Round_up = toward +Infinity, and + FPI_Round_down = toward -Infinity +given in gdtoa.h. + +Field fpi->sudden_underflow indicates whether strtodg should return +denormals or flush them to zero. Normal floating-point numbers have +bit fpi->nbits in the bits array on. Denormals have it off, with +exponent = fpi->emin. Strtodg provides distinct return values for normals +and denormals; see gdtoa.h. + +Compiling g__fmt.c, strtod.c, and strtodg.c with -DUSE_LOCALE causes +the decimal-point character to be taken from the current locale; otherwise +it is '.'. + +Source files dtoa.c and strtod.c in this directory are derived from +netlib's "dtoa.c from fp" and are meant to function equivalently. +When compiled with Honor_FLT_ROUNDS #defined (on systems that provide +FLT_ROUNDS and fegetround() as specified in the C99 standard), they +honor the current rounding mode. Because FLT_ROUNDS is buggy on some +(Linux) systems -- not reflecting calls on fesetround(), as the C99 +standard says it should -- when Honor_FLT_ROUNDS is #defined, the +current rounding mode is obtained from fegetround() rather than from +FLT_ROUNDS, unless Trust_FLT_ROUNDS is also #defined. + +Compile with -DUSE_LOCALE to use the current locale; otherwise +decimal points are assumed to be '.'. With -DUSE_LOCALE, unless +you also compile with -DNO_LOCALE_CACHE, the details about the +current "decimal point" character string are cached and assumed not +to change during the program's execution. + +On machines with a 64-bit long double and perhaps a 113-bit "quad" +type, you can invoke "make Printf" to add Printf (and variants, such +as Fprintf) to gdtoa.a. These are analogs, declared in stdio1.h, of +printf and fprintf, etc. in which %La, %Le, %Lf, and %Lg are for long +double and (if appropriate) %Lqa, %Lqe, %Lqf, and %Lqg are for quad +precision printing. + +Please send comments to David M.
