Random Number Generating Methods

These methods create reproducible sequences of random numbers given an initial seed value.

This methods rely on the pure-rand project.

random

Generates random numbers using the Mersenne Twister generator whose values are within the range 0 to 0xffffffff.

const SEED = 5
const sequence: Seq<number> = random(SEED)

type random = (seed = DEFAULT_SEED) => Seq<number>

Generates random numbers using the Mersenne Twister generator whose values are within the range 0 to 0xffffffff.

const SEED = 5
const sequence: Seq<number> = mersenne(SEED)

type mersenne = (seed = DEFAULT_SEED) => Seq<number>

Generates random numbers using the xorshift128+ generator whose values are within the range -0x80000000 to 0x7fffffff.

const SEED = 5
const sequence: Seq<number> = xorshift128plus(SEED)

type xorshift128plus = (seed = DEFAULT_SEED) => Seq<number>

Generates random numbers using the xoroshiro128+ generator whose values are within the range -0x80000000 to 0x7fffffff.

const SEED = 5
const sequence: Seq<number> = xoroshiro128plus(SEED)

type xoroshiro128plus = (seed = DEFAULT_SEED) => Seq<number>

Generates random numbers using a Linear Congruential generator whose values are within the range 0 to 0x7fff.

const SEED = 5
const sequence: Seq<number> = congruential(SEED)

type congruential = (seed = DEFAULT_SEED) => Seq<number>

Generates random numbers using a Linear Congruential generator whose values are within the range 0 to 0xffffffff.

const SEED = 5
const sequence: Seq<number> = congruential32(SEED)

type congruential32 = (seed = DEFAULT_SEED) => Seq<number>
