Ignoring other issues, what happens when you exceed the limits for float? Throw an exception, or change to another code path (int/long)? If the latter, might as well just use it in all cases - makes it more accurate and less complicated. > I suspect that this is adequate for "casual" users.

Python 2.5+ - and then only after a PEP that's gone through as rigorous a process as this one IMO. Tim Delaney
