Well, you can search comp.lang.c about a thread on what type to use
(int/long/double/etc.) to represent dollar amounts (including the
cents).  I don't think there is a clear answer that representing dollar
amounts with floating point is a bad idea.  It depends on what kinds of
operations you are going to do, which in this case is a division.
