x(n+1) = 16807 * x(n) mod (m).
x(n+1) = 16807 * x(n) mod (m)
where 16807 == 7^5.
We split up the calculations to avoid overflow.
h = last / q; l = x - h * q; t = a * l - h * r
h = last / q; l = last % q; t = a * l - h * r
m = 2147483647, a = 16807, q = 127773, r = 2836
There are lots of other combinations of constants to use; look at
