Detailed Description

Arbitrary precision arithmetic.

This is used by the AlgRemez class It is a wrapper around the GNU Multiprecision Library (GMP).GMP library. and therefore can only be used if the CPS is built with GMP. This is achieved at CPS configure time by using the option --enable-gmp=GMP_PATH with the configure script, where GMP_PATH is the directory where GMP has been installed.
