hackage.haskell.org : random
This package provides basic pseudo-random number generation, including the ability to split random number generators. In pure code, use System.Random.uniform and System.Random.uniformR from System.Random to generate pseudo-random numbers with a pure pseudo-random number generator like System.Random.StdGen. As an example, here is how you can simulate rolls of a six-sided die using System.Random.uniformR: See System.Random for more details. In monadic code, use System.Random.Stateful.uniformM and System.Random.Stateful.uniformRM from System.Random.Stateful to generate pseudo-random numbers with a monadic pseudo-random number generator, or using a monadic adapter. As an example, here is how you can simulate rolls of a six-sided die using System.Random.Stateful.uniformRM: The monadic adapter System.Random.Stateful.runStateGen_ is used here to lift the pure pseudo-random number generator pureGen into the System.Random.Stateful.StatefulGen context. The monadic interface can also be used with existing monadic pseudo-random number generators. In this example, we use the one provided in the mwc-random package: See System.Random.Stateful for more details.
