Issue #7518: Move substitute definitions of C99 math functions from

2009-12-21T15:22:00+00:00

pymath.c to Modules/_math.c.

Issue #7117 (backport py3k float repr) continued:

2009-10-24T13:28:38+00:00

 - add double endianness detection to configure script
 - add configure-time check to see whether we can use inline
   assembly to get and set x87 control word in configure script
 - add functions to get and set x87 control word in Python/pymath.c
 - add pyport.h logic to determine whether it's safe to use the
   short float repr or not

Backport r71704 (add configure check for C99 round function) to trunk.

2009-04-18T14:41:37+00:00

copysign shouldn't be declared as static in pymath.c

Issue #4575: fix Py_IS_INFINITY macro to work correctly on x87 FPUs.

2009-02-09T14:18:43+00:00

It now forces its argument to double before testing for infinity.

any platform without HAVE_LOG1P should have DBL_EPSILON in

Part of source_os2emx.patch in issue 3868
Reviewed by Amaury Forgeot d'Arc

I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.

The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
