What semantics do you want for the arithmetic? For example,
IEEE floats have saturation (using infinity), but once you
get there you stay there. It sounds like what you want is
different, in that subtraction from the high limit gets you
back down. That has various effects, such as making addition
no longer be associative, so you could very easily write
erroneous programs which would trigger saturation effects
on some platforms but not others.
