No, most hardware (e.g., all flavors of x86) just sets a flag indicating that an overflow has occurred; it's up to the executing program to check the flag. Some CPUs have the capability of optionally generating an interrupt if the condition occurs, but again, that's under program control. And, of course, the mechanisms for integer and floating point operations are usually completely independent (partly because the Intel floating point was originally on a co-processor). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
