geometric_distribution Class

Generates a geometric distribution.

template<class IntType = int,
    class RealType = double>
    class geometric_distribution {
public:
    typedef T1 input_type;
    typedef IntType result_type;
    struct param_type;
    explicit geometric_distribution(RealType p0 = RealType(0.5));
    explicit geometric_distribution(const param_type& par0);
    RealType p() const;
    param_type param() const;
    void param(const param_type& par0);
    void reset();
    template<class Engine>
        result_type operator()(Engine& eng);
    template<class Engine>
        result_type operator()(Engine& eng,
            const param_type& par0);
private:
    RealType stored_p;          // exposition only
    };

Parameters

• IntType
  The integer result type.

• RealType
  The floating-point engine value type.

Remarks

The template class describes a distribution that produces values of a user-specified integral type with a geometric distribution.
