產生分隔整數散發。

template<class IntType = int>
    class discrete_distribution {
public:
    typedef IntType result_type;
    struct param_type;
    discrete_distribution();
    explicit discrete_distribution(const param_type& par0);
    template<class Fn>
        discrete_distribution(size_t count,
            double low, double high, Fn func);
    explicit discrete_distribution(const param_type& par0);
    std::vector<double> probabilities() const;
    param_type param() const;
    void param(const param_type& par0);
    result_type min() const;
    result_type max() const;
    void reset();
    template<class Engine>
        result_type operator()(Engine& eng);
    template<class Engine>
        result_type operator()(Engine& eng,
            const param_type& par0);
