In computing, FLOPS or flops (an acronym for FLoating-point Operations Per Second) is a measure of computer performance, useful in fields of scientific calculations that make heavy use of floating-point calculations. For such cases it is a more accurate measure than the generic instructions per second.Although the final S stands for "second", singular "flop" is often used, either as a back formation or an abbreviation for "FLoating-point OPeration"; e.g.
