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 2.3.0 supports Python 3.14 and free-threaded builds,
- Preliminary support for free-threaded builds.
- Fix behavior and memory leaks for contexts.
- Fix memory leaks for mpfr caching.
- Fix rounding error in float(mpz).
- Add missing methods to mpz and mpq.
- Fix round(mpz, ndigits) if ndigits is negative.
- Improved support for mixed mpfr and mpc arithmetic.
- Many bug fixes.
- Initial support for free-threaded builds.
- Bug fix: use C int instead of C char for some internal code.
- Bug fix: add xmpz.bit_count method.
gmpy2 2.2.0 is now available with support for Python 3.7 to 3.13.
- Support for thread-safe contexts and context methods has been improved.
- Interoperability with Cython extensions has been updated.
- Extensive improvements have been made to the build and testing processes.
- Many bug fixes.
- Extensive documentation cleanup.
