GMP/MPIR, MPFR, and MPC interface to Python 2.6+ and 3.x

Project description

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.

Release 2.0.4 has the following fixes:

  1. bit_scan0() no longer returns -1 after the last 0-bit is reached.

  2. A performance regression with mpmath and Python 3.x has been fixed.

  3. divm() no longer mutates the arguments in certain circumstances.
