Ah, sorry -- I didn't parse this properly the first time through. You
should also be aware of the limitations of representing a decimal
fractions as a float. I'll defer to the docs, instead of trying (and
failing) to explain this myself: http://docs.python.org/tut/node16.html

Also, have a look in the standard library, there was a module added in
2.4 which will provide additional assistance.

HTH,
