FLOPS = FLoating-point Operations Per Second. Think fast! What’s 372236068.318888 divided by 0.000200020150189915? Are you done yet? How about now?
(In other words, for all practical purposes, the answer is zero. That's not to say that the brain isn’t incredibly powerful—it is—but if you want to measure its speed, you’ll have to find a more appropriate benchmark than floating-point operations per second.)
