As others have suggested, it's best to avoid floating point for finances. 
There's a reason databases, Java and C# (among others) have 
fixed-point, "decimal" types.

For instance, the Python tutorial has a decent description of floating point 
representation problems: http://docs.python.org/tut/node16.html

Working accurately and precisely with floating point is actually quite 
complex; be careful if you're not good at numerical analysis.
