RandomXorshift

A cryptographically unsecure 128-bit Xorshift pseudo-random number generator.

Instance properties

var max:UInt32 { get }

The maximum unsigned integer value the random number generator is capable of producing.

Instance methods

mutating func generate() -> UInt32

Generates a pseudo-random 32 bit unsigned integer, and advances the random number generator state.

mutating func generate(less_than maximum:UInt32) -> UInt32

Generates a pseudo-random 32 bit unsigned integer less than maximum, and advances the random number generator state. This function should be preferred over using the plain generate() method with the modulo operator to avoid modulo biasing. However, if maximum is a power of two, a bit mask may be faster.
