This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

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

0.1.3.4

  • 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.
