This is a Python implementation of IBM's proposed standard for decimal arithmetic: http://www2.hursley.ibm.com/decimal/ and is quite an involved piece of work. The integration with Python will be weak at first, and it's probably more important to work on that. For example, the builtin round() function won't know what to do with Decimal instances, and neither will float format codes (e.g., '"%10.3f" % some_Decimal' won't work in a reasonable way at first). Involved as it already is, it's just a start at a complete numeric facility.
