27-Aug-09 Anonymous - be aware that multiplying by -1 turns negative numbers positive, but
doesn't protect against being passed a positive number by mistake. You may also want to check
and make sure you don't inadvertently lose precision (this is a problem in other languages),
and keep an eye out for underflow/overflow. The ABS function does that for you.
