It would lead to some hilarious malpractise if anyone understood floating point and stole a billion cents. Things like this has happend and will continue if people arent aware of floating point error.

> of floating point error.

Worth noting that this is a risk whenever there is rounding, if this chain of logic happens with cents as ints, it is still wrong:

    1 / 2 => 0
    0 * 2 => 0
Therefore:

    1 == 0
