# What exactly is a FLOP?

I know that is a "FLoating-point Operation" but,what exactly mean this!? Can anyone make me a mathematical example of a FLOP?

For example, is $\sqrt{2}$ a FLOP?

• The Green Lantern movie was a FLOP. With a capital F. Commented Mar 18, 2013 at 20:48
• @AsafKaragila and a capital LOP it seems :) Commented Mar 18, 2013 at 20:53

No a floating point operation is an operation like $+$ $-$ $\cdot$ or $/$, where the numbers and the result are both floating point numbers.

• So, $\frac{1.5}{2.33}=0.644$ is a FLOP right? Commented Mar 18, 2013 at 21:26
• calculating it takes a flop yes Commented Mar 18, 2013 at 21:27
• What do you mean with the words "it takes a flop"? Commented Mar 18, 2013 at 21:36
• as i know flop it is a measurement of the complexity, it is not a real calculation Commented Mar 18, 2013 at 21:39
• Ahh, I have understand, one FLOP is a elementary operation, in the forms mentioned above, is correct? Commented Mar 18, 2013 at 21:59
