With floating point, that's not a problem.
What you're talking about is NOT a problem with integer money. Integers have
unlimited precision, they are as large as you need them to be, there is no such
thing as overflowing them. When you're using a computer to represent the
integers, you just use a data type capable of representing the largest integers
you could ever possibly need to use for storage or intermediate calculations, if
necessary a variable size representation such as BigInt or binary-coded-decimal.
