Standard Deviation Calculator

I couldn't make this as fun as the Mean Machine, in fact it is basically all numbers. (If anyone can think of how to make it more fun, please say!)

Here it is: Standard Deviation Calculator

Is it right?

Re: Standard Deviation Calculator

Bug: It almost looks like you got a pentium bug.

Enter 2, 13, 13, 7, 9

The last difference is 0.1999999999 when it should be 0.2

It copies over (expectedly) to the square of the difference.
