Normal distribution using Box–Muller transform
Uses the Box–Muller transform to generate <count> normally distributed random numbers and displays the frequency.
Use the <standard deviation> slider to change the standard deviation and the <count> slider to change the number of numbers generated between displays..
The main function takes two parameters:
sigma: standard deviation
I've added a random function (see inside) that takes min, max, and sigma as parameters. The <sigma> parameter let's you determine how many standard deviations you would like to include in your result. The higher you set it the less likely it is for the result to land anywhere near your min/max bounds.
