System.Random.TF
Description
This module exports System.Random.TF.Gen and System.Random.TF.Init
modules without exporting the alternative RandomGen
class from System.Random.TF.Gen. To use this class and the Random
instances written for it, please import System.Random.TF.Gen and System.Random.TF.Instances
directly.

seedTFGen :: (Word64, Word64, Word64, Word64) -> TFGen Source #
Create a generator from a random seed.
Derive a new generator instance from the global RNG using split.
This is the default way of obtaining a new RNG instance.
Initial generator is seeded using mkSeedUnix on UNIX,
and mkSeedTime otherwise. This should be eventually
replaced with proper seeding.
mkTFGen :: Int -> TFGen Source #
Quick and dirty way of creating a deterministically seeded generator.
