You have two options: use floating point and round manually or use the
new Decimal class and specify your precision.  However, if you restrict
your calculations, you will have errors after chaining more than one or
two operations.  Your best bet is to perform rounding only at the end of
your calculations, at which point you can either round the result
directly or round for display only (by using appropriate % formatting).
