SeedableRandomNumberGenerator

public class SeedableRandomNumberGenerator : RandomNumberGenerator

A basic implementation of a random number generator that can be given a seed. It depends on srand48() and drand48(), so any calls to those two functions outside of this class will impact the reproducibility of the generator.

  • Creates a new instance and seeds the generator using a call to srand48(seed).

    Declaration

    Swift

    public init(seed: Int = 0)

  • Generates the next random number; uses drand48().

    Declaration

    Swift

    public func next() -> UInt64
