The following listing contains the interface of the GMP unit.
This unit provides an interface to the GNU Multiprecision Library to perform arithmetic on integer, rational and real numbers of unlimited size and precision.
To use this unit, you will need the gmp library which can be found in http://www.gnu-pascal.de/libs/.
{ Definitions for GNU multiple precision functions: arithmetic with
integer, rational and real numbers of arbitrary size and
precision.
Translation of the C header (gmp.h) of the GMP library. Tested
with GMP 3.x and 4.x.
To use the GMP unit, you will need the GMP library which can be
found in http://www.gnu-pascal.de/libs/
