public class MersenneTwister64
extends MersenneTwister

Same as `MersenneTwister` except that method `raw()` returns 64 bit random numbers instead of 32 bit random numbers.

Constructor Detail

### MersenneTwister64

    public MersenneTwister64()

  Constructs and returns a random number generator with a default seed, which is a constant.

### MersenneTwister64

    public MersenneTwister64(int seed)

  Constructs and returns a random number generator with the given seed.

Parameters:
  `seed` - should not be 0, in such a case `MersenneTwister64.DEFAULT_SEED` is silently substituted.

### MersenneTwister64

    public MersenneTwister64(Date d)

  Constructs and returns a random number generator seeded with the given date.

Parameters:
  `d` - typically `new java.util.Date()`

Method Detail

### raw

    public double raw()

  Returns a 64 bit uniformly distributed random number in the open unit interval `(0.0,1.0)` (excluding 0.0 and 1.0).

  Overrides:
    `raw` in class `RandomEngine`
