cauchy_distribution::operator()

Returns 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 <random> eng as a source of uniformly distributed random integral values and returns floating-point values with each value x occurring with probability:

pr(x) = 1 / (pi * b (1 + (( x - a ) / b)²))

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