Hardware Traps for Integer Overflow

[Wanderer via Digitalmars-d]

I don't see any valid alternatives. What should ideally happen if 
you increment 0xFFFF..FFFF? Should the value remain the same? 
That's not much better than resetting back to zero, still a 
mathematical error. Throw an exception? That would kill 
performance and break lots of existing code.

If you need perfect calculations, you can always use an according 
library for numbers with arbitrary precision.
