Introduction

Seeded non-cryptographic PRNG. Import std/random to bind the module as random. Call free functions as random.name(...). Struct methods use a receiver value.

/ std/random

This page is the package reference for std/random. Private helpers used only by co-located tests are not listed.

Functions

Seeds the non-crypto PRNG. Call form: random.seed(s).

/ std/random

random.seed(1)

Parameters: s: integer seed. Returns: None.

u64

Returns the next non-crypto PRNG integer. Call form: random.u64().

/ std/random

random.seed(1)
$ n = random.u64()

Parameters: No parameters. Returns: Integer random value.

float

Returns the next non-crypto PRNG float in [0, 1). Call form: random.float().

/ std/random

random.seed(1)
$ x = random.float()

Parameters: No parameters. Returns: Float random value.
