Module Random: pseudo-random number generator

val init : int -> unit

Initialize the generator, using the argument as a seed. The same seed will always yield the same sequence of numbers.

val full_init : int array -> unit

Same as init but takes more data as seed.

val bits : unit -> int

Return 30 random bits in a nonnegative integer.

val int : int -> int

Random.int bound returns a random number between 0 (inclusive) and bound (exclusive). bound must be positive and smaller than 2^{30}.

val float : float -> float

Random.float bound returns a random number between 0 (inclusive) and bound (exclusive).
