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. - |
