RandomUInt

Returns a random unsigned integer in a half-open range.

Module: Std::Random

Signature

One function per unsigned-integer width:

func RandomUInt8(min: uint8, max: uint8, seed: uint64) -> uint8;
func RandomUInt16(min: uint16, max: uint16, seed: uint64) -> uint16;
func RandomUInt32(min: uint32, max: uint32, seed: uint64) -> uint32;
func RandomUInt64(min: uint64, max: uint64, seed: uint64) -> uint64;
func RandomUInt(min: uint, max: uint, seed: uint64) -> uint;

Parameters

Name	Type	Description
min	unsigned	Inclusive lower bound.
max	unsigned	Exclusive upper bound. Must be > min.
seed	uint64	Seed value that determines the result.

Returns

A value in the half-open range [min, max) — min is possible, max is not.

WARNING

min must be strictly less than max, otherwise the call aborts via Fatal.

Example

import Std::Random;

let index = Random::RandomUInt(0u, count, seed);   // pick an array slot
