Constructor Detail

Pascal

public Pascal(double prob,
              int successes)

the seed is aumatically provided by the SeedGenerator

Parameters:

prob - : 0 < prob < 1

successes - : successes > 0

Pascal

public Pascal(double prob,
              int successes,
              long seed)

The constructor with which a specific seed is set for the random number generator

Parameters:

prob - : 0 < prob < 1

successes - : successes > 0

seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers

Method Detail

sample

public long sample()

Generate a new random number.

Specified by:

sample in interface DiscreteGenerator

Returns:

The next random number in the sequence
