The bigfloat package is a Python package providing arbitrary-precision
correctly-rounded binary floating-point arithmetic.
Features
* correct rounding on all operations; precisely defined semantics compatible
with the IEEE 754-2008 standard.
* support for mixed-type operations with Python integers and floats
* 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.
