A warning on things like BigDecimal.
Unless I'm mistaken it's still stored in twos compliment, which means
you'll still end up with the same sort of floating point problems
(albeit further down), and the same numbers that you can't express
exactly with a normal float, can't be expressed exactly with a
BigDecimal.

You'd think some fixed point math libraries would help, but be
careful, because many of those _also_ store in twos compliment.
