bigfloat 0.2.1 / 0.3.0 Alpha 2
Arbitrary precision correctly-rounded floating point arithmetic, via MPFR
bigfloat is a Python library that provides arbitrary-precision correctly-rounded floating-point arithmetic. It is implemented as a wrapper around the MPFR library.
- correct rounding on all operations; precisely defined semantics compatible with the IEEE 754-2008 standard.
- the BigFloat type interacts well with Python integers and floats.
- full support for emulating IEEE 754 arithmetic in any of the IEEE binary interchange formats described in IEEE 754-2008. Infinities, NaNs, signed zeros, and subnormals are all supported.
- easy control of rounding modes and precisions, via Python's 'with' statement.
