Most random number generators produce uniform-distributed
random numbers, not normally -distributed random numbers.
There's an old programmer's trick (at least as old as
FORTRAN 4) to approximate normal distributions from uniform
ones.... take TWO uniform randoms of half the range and add
them together to get final value!
Hope this helps
