gmpy2 is a C-coded Python extension module that supports multiple-precision\\ arithmetic. gmpy2 is the successor to the original gmpy module. The gmpy module\\ only supported the GMP multiple-precision library. gmpy2 adds support for the\\ MPFR (correctly rounded real floating-point arithmetic) and MPC (correctly\\ rounded complex floating-point arithmetic) libraries. gmpy2 also updates the\\ API and naming conventions to be more consistent and support the additional\\ functionality. \\ \\
