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).
gmpy2 2.1 was extensively refactored. Some of the significant changes are:
* Support for thread-safe contexts and context methods
* Interoperability with Cython extensions
* mpz and mpq operation can release the GIL (controlled by the conntext)
* Improved argument processing
gmpy2 is available at https://pypi.python.org/pypi/gmpy2/
