I tend to favor using floating point, doing calculations in pennies, and 
explicitly rounding result to nearest full penny. This is almost the same as 
using longs except that division does not always truncate numbers. 
Fractional pennies are often useful in intermediate results.

If there is some more appropriate type to use, I might be easily convinced 
otherwise. However, I don't think using some indefinite precision number 
type is a fits-for-all solution either, since...
