Hello Dr. Math,

I really need to know what a flop is, and what a teraflop is. My
teacher told me to go to this site, but I can't find it anywhere. Can

Dear John,

It's not flop, it's flops. Flops stands for "FLoating-point Operations
Per Second," and we don't use "flop."

A computer has different ways of representing numbers internally.
Integers are the easiest, but they have to be whole numbers between
-32,768 and 32,767. Integers multiply and divide quickly. "Floating
point" numbers are the opposite. They're numbers that can have a
decimal point as part of them, and a power of ten, which is the way
the computer can tell 75.0 from 0.075 or 750,000,000.

Flops are a measure of computer speed. A "1 flops" computer can
perform one multiplication of floating point numbers in a second.

A modern computer can multiply billions of floating point numbers in
one second. Each billion multiplications in a second is a "gigaflops."
A thousand billion multiplications per second is a "teraflops," and I
think the biggest of today's computers can do that.
