gmpy2 is an optimized, C-coded Python extension module that supports fast multiple-precision arithmetic. gmpy2 is based on the original gmpy module. gmpy2 adds support for correctly rounded multiple-precision real arithmetic (using the MPFR library) and complex arithmetic (using the MPC library).

Releases are available in the Python Package Index (PyPI) at https://pypi.python.org/pypi/gmpy2/. Documentation is available at https://gmpy2.readthedocs.io/.
