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 integer between 0 (inclusive)
and bound (exclusive). bound must be more than 0 and less
than 2^{30}.
val float : float -> float
-
Random.float bound returns a random floating-point number
between 0 (inclusive) and bound (exclusive). If bound is
negative, the result is negative. If bound is 0, the result
is 0.
