Methods overloadedMethod :: MethodProxy RandSetSeedMethodInfo Rand -> signature -> s #

randSetSeed Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Rand	`rand_`: a `Rand`
-> Word32	`seed`: a value to reinitialize the random number generator

Sets the seed for the random number generator Rand to seed.

Instances

((~) * signature (Word32 -> Word32 -> m ()), MonadIO m) => MethodInfo * RandSetSeedArrayMethodInfo Rand signature Source #

randSetSeedArray Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Rand	`rand_`: a `Rand`
-> Word32	`seed`: array to initialize with
-> Word32	`seedLength`: length of array
-> m ()

Initializes the random number generator by an array of longs. Array can be of arbitrary size, though only the first 624 values are taken. This function is useful if you have many low entropy seeds, or if you require more then 32 bits of actual entropy for your application.
