wip/py-bigfloat 0.2.1nb2 NetBSD

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.
