type t

Default values

val default : unit -> rng_type

val default_seed : unit -> nativeint

val set_default : rng_type -> unit

val set_default_seed : nativeint -> unit

val env_setup : unit -> unit

Creating

val make : rng_type -> t

val set : t -> nativeint -> unit

val name : t -> string

val get_type : t -> rng_type

warning : the nativeint used for seeds are in fact unsigned but ocaml treats them as signed. But you can still print them using %nu with printf functions.

val max : t -> nativeint

val min : t -> nativeint

val memcpy : t -> t -> unit

val clone : t -> t

val dump_state : t -> string * string

val set_state : t -> (string * string) -> unit

Sampling

val get : t -> nativeint

val uniform : t -> float

val uniform_pos : t -> float

val uniform_int : t -> int -> int

These function fill the array with random numbers :

val uniform_arr : t -> float array -> unit

val uniform_pos_arr : t -> float array -> unit
