Methods

showsPrec :: Int -> GenTopPolicy -> ShowS

show :: GenTopPolicy -> String

showList :: [GenTopPolicy] -> ShowS

generateParams

Arguments

:: MonadRandom m

=> Int

number of bits

-> Maybe GenTopPolicy

top bit policy

-> Bool

force the number to be odd

-> m Integer

Generate a number for a specific size of bits, and optionaly set bottom and top bits

If the top bit policy is Nothing, then nothing is done on the highest bit (it's whatever the random generator set).

If @generateOdd is set to True, then the number generated is guaranteed to be odd. Otherwise it will be whatever is generated

generateMax

Arguments

:: MonadRandom m

=> Integer

range

-> m Integer

Generate a positive integer x, s.t. 0 <= x < range

generateBetween :: MonadRandom m => Integer -> Integer -> m Integer

generate a number between the inclusive bound [low,high].
