Primitive RNG Bit Generator

Source: R/primitives.R
prim_rng_bit_generator.Rd

Generates pseudo-random numbers using the specified algorithm and returns the updated RNG state together with the generated values.

Usage

prim_rng_bit_generator(
  initial_state,
  rng_algorithm = "THREE_FRY",
  dtype,
  shape
)

Arguments

initial_state

(arrayish)
RNG state (ui64[2]).

rng_algorithm

(character(1))
RNG algorithm name. Default is "THREE_FRY".

dtype

(character(1) | tengen::DataType)
Data type of the generated random values.

shape

(integer())
Shape.

Value

list of two arrayish values:
The first element is the updated RNG state with the same dtype and shape as initial_state. The second element is an array of random values with the given dtype and shape.

Implemented Rules
