-BCMATH FAQ:
-
-1) Why BCMATH?
-
-The math routines of GNU bc become more generally useful in a
-library form. By separating the BCMATH library from GNU bc,
-GNU bc can be under the GPL and BCMATH can be under the LGPL.
-
-2) Why BCMATH when GMP exists?
-
-GMP has "integers" (no digits after a decimal), "rational numbers"
-(stored as 2 integers) and "floats". None of these will correctly
-represent a POSIX BC number. Floats are the closest, but will not
-behave correctly for many computations. For example, BC numbers have
-a "scale" that represent the number of digits to represent after the
-decimal point. The multiplying two of these numbers requires one to
-calculate an exact number of digits after the decimal point regardless
-of the number of digits in the integer part. GMP floats have a
-"fixed, but arbitrary" mantissa and so multiplying two floats will end
-up dropping digits BC must calculate.
