class RandomGen g
random System.Random System.Random.Stateful, random-fu Data.Random
RandomGen is an interface to pure pseudo-random number generators. StdGen is the standard RandomGen instance provided by this library.
class () => RandomGen g

RandomGen is an interface to pure pseudo-random number generators. StdGen is the standard RandomGen instance provided by this library.
class RandomGen g
tf-random System.Random.TF.Gen
Alternative RandomGen class with a modified next operation, and added splitn and level operations. Using the generator requires that no more than one operation is called on the same generator state, as the implementation does not guarantee pseudorandomness otherwise. As an exception, calling splitn many times on the same generator state is allowed as long as the 'bits' argument is the same for all the calls.
class RandomGen gen
foundation Foundation.Random
A Deterministic Random Generator (DRG) class
