Runs a random monad using the global RNG.

Fetches the generator inside the random monad.

randomM :: (RandomGen g, Random a) => RandomM g a Source #

Generates a random value inside the random monad.

randomRM :: (RandomGen g, Random a) => (a, a) -> RandomM g a Source #

Generates a bounded random value inside the random monad.

nRandomsR :: (RandomGen g, Random a) => Int -> ([a], [a]) -> RandomM g [a] Source #

Generates n random values in the given range without consuming the generator.

nRandoms :: (RandomGen g, Random a) => Int -> RandomM g [a] Source #

Generates n random values without consuming the generator.
