negative_binomial_distribution::operator()

Generates a random value.

template<class Engine>
    result_type operator()(Engine& eng);
template<class Engine>
    result_type operator()(Engine& eng,
        const param_type& par0);

Parameters

• eng
  The random engine.

• par0
  The parameter package used to return the random value.

Remarks

The first member operator uses the engine eng as a source of uniformly distributed random integral values and returns integral values with each value i occurring with probability:

Pr(i) = (i / (k + i - 1)) * p^k * (1 - p)^i

The second member function behaves the same, except that it uses the parameters stored in par0.
