Alias `std.random.Mt19937_64`

A MersenneTwisterEngine instantiated with the parameters of the original engine MT19937-64, generating uniformly-distributed 64-bit numbers with a period of 2 to the power of 19937.


						
				alias Mt19937_64
				 = MersenneTwisterEngine!(ulong,64L,312L,156L,31L,-5403634167711393303L,29L,6148914691236517205L,17L,8202884508482404352L,37L,-2270628950310912L,43L,6364136223846793005L);

Example

// Seed with a constant
auto gen = Mt19937_64(12345);
auto n = gen.front; // same for each run
writeln(n); // 6597103971274460346

// Seed with an unpredictable value
gen.seed(unpredictableSeed);
n = gen.front; // different across runs
