1.13.1.36 rand

‘rand(0)‘ returns a pseudo random number in the interval [0:1] generated

           from the current value of two internal 32-bit seeds.

‘rand(-1)‘ resets both seeds to a standard value. ‘rand(x)‘ for x>0 sets both seeds to a value based on the value of x. ‘rand({x,y})‘ for x>0 sets seed1 to x and seed2 to y.
