Pseudo-random number generator (PRNG).
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
val self_init :
unit -> unit
Initialize the generator with a more-or-less random seed chosen
in a system-dependent way.
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)
bound must be more than 0 and less
val float :
float -> float
Random.float bound returns a random floating-point number
between 0 (inclusive) and
bound (exclusive). If
negative, the result is negative. If
bound is 0, the result
val bool :
unit -> bool
Random.bool () returns
false with probability 0.5 each.
Values of this type are used to store the current state of the
val get_state :
unit -> state
Returns the current state of the generator. This is useful for
checkpointing computations that use the PRNG.
val set_state :
state -> unit
Resets the state of the generator to some previous state returned by
