Arbitrary precision correctly-rounded floating point arithmetic, via MPFR.
Project description
The bigfloat package is a Python package providing arbitrary-precision correctly-rounded floating-point arithmetic. It is implemented as a wrapper around the MPFR library (http://www.mpfr.org).
Features:
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.
