It could be used anywhere where you wanted to determine if a player entered a command wrong or something to that effect. Normally you'd want to keep the deviation value low if you're doing that.

It was just an exercise though, and I figured it could save someone trouble if they ever needed it.

Anyways, you could just add it onto my pile of useless crap that no one cares about that I've posted in here, like Boyer-Moore, introsort, heapsort, quicksort, bitap, Rijndael, etc.
