Never decide that "nobody would need numbers bigger than X". Someone
will. One common thing to do with big numbers is to use the pieces
separately; although I would never recommend floating point for
encoded numbers like that. But I quite happily treat BIND serial
numbers as straightforward integers, and they're usually something
like 2011072203 for the 3rd change on the 22nd of July 2011. That's a
fairly small example (in fact, BIND requires that serial numbers fit
inside a 32-bit integer, IIRC), but there are plenty of other examples
of numbers that get big fast because of that sort of thing.
