Method Details

nextDouble

public double nextDouble()

Returns the next random number in the sequence.

Specified by:

nextDouble in interface RandomNumberGenerator1D

Returns:

The next random number in the sequence.

nextDoubleFast

public double nextDoubleFast()

Description copied from interface: RandomNumberGenerator1D
