pcg-random

Haskell bindings to the PCG random number generator http://www.pcg-random.org.

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict.

Implements the standard multiple stream generator as well as the fast, single and unique variants.

The api is very similar to mwc-random but the pcg generator appears to be slightly faster. There is also a pure interface via the random libray.

Changes

0.1.3.5

Build with ghc-8.4

0.1.3.4

Fix byte array bugs in System.Random.PCG.Pure

0.1.3.3

Added System.Random.PCG.Pure module.

0.1.3.2

Added System.Random.PCG.Fast.Pure module.

0.1.3.1

Added withFrozen function.

0.1.3.0

Use entropy package for system random generator.

0.1.2.0

Allow primitive-0.6.

0.1.1.0

Add uniformB, a function to generate a bounded random number in [0,b) range. This preforms significantly faster than uniformR (0,b-1).
Add type specific versions for uniformR and uniformB.

0.1.0.1

Fix bug when dealing with Word and Int types.
