Sourcetype t

Default values

Sourceval default : unit -> rng_type
Sourceval default_seed : unit -> nativeint
Sourceval set_default : rng_type -> unit
Sourceval set_default_seed : nativeint -> unit
Sourceval env_setup : unit -> unit

Creating

Sourceval make : rng_type -> t
Sourceval set : t -> nativeint -> unit
Sourceval name : t -> string
Sourceval 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.

Sourceval max : t -> nativeint
Sourceval min : t -> nativeint
Sourceval memcpy : t -> t -> unit
Sourceval clone : t -> t
Sourceval dump_state : t -> string * string
Sourceval set_state : t -> (string * string) -> unit

Sampling

Sourceval get : t -> nativeint
Sourceval uniform : t -> float
Sourceval uniform_pos : t -> float
Sourceval uniform_int : t -> int -> int

These function fill the array with random numbers :

Sourceval uniform_arr : t -> float array -> unit
Sourceval uniform_pos_arr : t -> float array -> unit
