GMPY2 is a wrapper for GMP and MPFR multiple-precision arithmetic libraries. If you have an interest in multiple-precision arithmetic or want more control over the handling of exceptional events in floating point arithmetic, please check out GMPY2! GMPY2 is available for download from: http://code.google.com/p/gmpy/ Experimental release -------------------- To simplify the codebase, allow for changes in the API, and support simultaneous installation, the development version has been renamed to GMPY2. The following is list of changes in GMPY2: In 2.0.0a0 ---------- * support for a mutable integer type "xmpz" * removal of random number functions * "xmpz" supports slices for setting/clearing bits * some methods have been renamed (scan1 -> bit_scan1) * support for Python prior to 2.6 has been removed * support for all division modes has been added * ceiling - round to +Infinity * floor - round to -Infinity * truncate - round to zero * 2exp - division by a power of 2 * support is_even() and is_odd() In 2.0.0a1 ---------- * support for the MPFR floating point library In 2.0.0a2 ---------- * context manager support from controlling MPFR arithmetic * can raise Python exceptions when exceptional events occur with MPFR arithmetic; for example, comparing against "nan" can trigger an exception * more complete coverage for MPFR * many function names were changed to be more consistent Please report any issues! casevh
