Notes on Randomness

This random number generator uses the mt_rand PHP function to do the actual number generation. I choose to use the Mersenne Twister function because it’s about four times faster. It will return a random positive or negative integer inclusively between the values you specify. The maximum value for either is 2147483647. I've found this to be very useful for giveaways at meetings.
