Module documentation for 1.1

The Haskell Standard Library -- Random Number Generation

Build Status

This library provides a basic interface for (splittable) random number generators.

The API documentation can be found here:

http://hackage.haskell.org/package/random/docs/System-Random.html

A module supplying this interface is required for Haskell 98 (but not Haskell 2010). An older [version] (http://www.haskell.org/ghc/docs/latest/html/libraries/haskell98/Random.html) of this library is included with GHC in the haskell98 package. This newer version, with compatible api, is included in the [Haskell Platform] (http://www.haskell.org/platform/contents.html).

Please report bugs in the Github [issue tracker] (https://github.com/haskell/random/issues) (no longer in the GHC trac).

Changes

1.1

  • breaking change to randomIValInteger to improve RNG quality and performance see https://github.com/haskell/random/pull/4 and ghc https://ghc.haskell.org/trac/ghc/ticket/8898
  • correct documentation about generated range of Int32 sized values of type Int https://github.com/haskell/random/pull/7
  • fix memory leaks by using strict fields and strict atomicModifyIORef' https://github.com/haskell/random/pull/8 related to ghc trac tickets #7936 and #4218
  • support for base < 4.6 (which doesnt provide strict atomicModifyIORef') and integrating Travis CI support. https://github.com/haskell/random/pull/12
  • fix C type in test suite https://github.com/haskell/random/pull/9
