Web25 Jul 2014 · My best approach in C seemed to be the following: if ( (a-=b)+b < b) { // underflow here } Basically, subtract b from a, and if result underflows detect it and do some conditional processing (which is unrelated to a's value, for example, it brings an error, etc). WebThe term arithmetic underflow (or "floating point underflow", or just "underflow") is a condition in a computer program where the result of a calculation is a number of smaller absolute value than the computer can actually store in memory. You don't have an overflow here: the result will be 01100100.
