 Description

-GMP/MPIR, MPFR, and MPC interface to Python 2.6+ and 3.x
+GMP/MPIR, MPFR, and MPC interface to Python
 
 gmpy2 is a C-coded Python extension module that supports
 multiple-precision arithmetic. In addition to supporting GMP or MPIR for
 multiple-precision integer and rational arithmetic, gmpy2 adds support
 for the MPFR (correctly rounded real floating-point arithmetic) and MPC
 (correctly rounded complex floating-point arithmetic) libraries.
