Methods

showsPrec :: Int -> MT19937 -> ShowS #

show :: MT19937 -> String #

showList :: [MT19937] -> ShowS #

init :: Word32 -> MT19937 Source #

Initialize an MT19937 with the given seed.

init' :: Word32 -> MT19937 Source #

Initialize an MT19937 with the given seed, without pre-twisting.

extract :: MT19937 -> (Word32, MT19937) Source #

Extract the next random byte and return the updated state.

skip :: Int -> MT19937 -> MT19937 Source #

Skip the given number of random bytes.

If the skips would result in multiple twists, we perform these in a single pass (rather than copying the array every twist).
