Easiest answer is to use integers. Scale everything up by a factor of
100, and you won't need floats at all. Just convert when printing (and
even then you may get into trouble).
Another answer is to use Decimal class, which CAN represent decimal
values exactly.
That only applies to decimal values which can be represented using a fixed
number of decimal places. So 1/5 is fine, and is 0.2 exactly, but 1/3 is not,
since it would require an infinite number of decimal places.
BTW, if this is supposed to represent US legal tender, you left out the
fifty-cent piece as well as the two dollar bill.
