Many high-level languages will do something similar, usually in the form of throwing exceptions. Keep in mind that raising errors on overflow is purely a software convention - the hardware will detect it any time it happens, but the software decides whether the overflow is actually a problem or not.

(Integer overflow, of course, isn't a problem for unsigned integers, so no errors are thrown when they "overflow.") |
