gmpy2: GMP/MPFR/MPC for Python

gmpy2 is an optimized, C-coded Python extension module that provides an interface to the GMP (GNU Multiple Precision Arithmetic Library), MPFR (Multiple-Precision Floating-point Reliable Library), and MPC (Multiple Precision Complex Library). It enables fast arbitrary-precision integer, rational, real, and complex arithmetic in Python. The current stable version is 2.3.0, and it is actively maintained with regular updates to support newer Python versions and fix bugs.
