Alias std.random.Xorshift128

Define XorshiftEngine generators with well-chosen parameters. See each bits examples of "Xorshift RNGs". Xorshift is a Xorshift128's alias because 128bits implementation is mostly used.

alias Xorshift128 = XorshiftEngine!(uint,128,11,-8,-19);

Example

// Seed with a constant
auto rnd = Xorshift(1);
auto num = rnd.front;  // same for each run
writeln(num); // 1405313047

// Seed with an unpredictable value
rnd.seed(unpredictableSeed);
num = rnd.front; // different across rnd
