I would _guess_ that the IEEE 754 floating point standard does require
that, but I haven't actually gotten my hands on a copy of the standard
yet. If it doesn't, I may have to stop writing code that depends on
the assumption that floating point computation is exact for exactly
representable integers. If so, then we're reasonably safe; there
aren't many non-IEEE machines left these days.
