%description
|
|
This package provides basic pseudo-random number generation, including the
|
|
ability to split random number generators.
|
|
|
|
== "System.Random": pure pseudo-random number interface
|
|
|
|
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':
|
|
|
|
>>> let roll = uniformR (1, 6) :: RandomGen g => g -> (Word, g) >>> let rolls =
|
|
unfoldr (Just . roll) :: RandomGen g => g -> [Word] >>> let pureGen = mkStdGen
|
|
42 >>> take 10 (rolls pureGen) :: [Word] [1,1,3,2,4,5,3,4,6,2]
|
|
|
|
See "System.Random" for more details.
|
|
|
|
== "System.Random.Stateful": monadic pseudo-random number interface
|
|
|
|
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':
|
|
|
|
>>> let rollM = uniformRM (1, 6) :: StatefulGen g m => g -> m Word >>> let
|
|
pureGen = mkStdGen 42 >>> runStateGen_ pureGen (replicateM 10 . rollM) ::
|
|
[Word] [1,1,3,2,4,5,3,4,6,2]
|
|
|
|
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
|
|
<https://hackage.haskell.org/package/mwc-random mwc-random> package:
|
|
|
|
>>> import System.Random.MWC as MWC >>> let rollM = uniformRM (1, 6) ::
|
|
StatefulGen g m => g -> m Word >>> monadicGen <- MWC.create >>> replicateM 10
|
|
(rollM monadicGen) :: IO [Word] [2,3,6,6,4,4,3,1,5,4]
|
|
|
|
See "System.Random.Stateful" for more details.
