(OT I know, but just so you know, you *may* get away with using floats
for financial calculations if you're handling small numbers of floats
of  roughly same order of magnitude, but if your calculations have to
be exact to the penny, and you have lots of numbers not of the same
magnitudes, you probably don't want to do this.
