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.
