(* 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. It is not
useful to give more than 55 integers. *)
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). *)
