RandomFloat

Returns a random floating-point value in a range.

Module: Std::Random

Signature

func RandomFloat32(min: float32, max: float32, seed: uint64) -> float32;
func RandomFloat64(min: float64, max: float64, seed: uint64) -> float64;

Parameters

Name	Type	Description
min	float32 / float64	Lower bound. Must be < max.
max	float32 / float64	Upper bound.
seed	uint64	Seed value that determines the result.

Returns

A value in the range [min, max], in the requested precision. The seed is scaled to a fraction of the full range and interpolated between the bounds.

WARNING

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

Example

import Std::Random;

let t = Random::RandomFloat64(0.0, 1.0, seed);     // unit interval
