설명

저장 된 값을 반환 하는 멤버 함수 stored_mean.

예제

 

// std_tr1__random__normal_distribution_mean.cpp 
// compile with: /EHsc 
#include <random> 
#include <iostream> 
 
typedef std::ranlux64_base_01 Myeng; 
typedef std::normal_distribution<double> Mydist; 
int main() 
    { 
    Myeng eng; 
    Mydist dist(1.5, 2.0); 
    Mydist::input_type engval = eng(); 
    Mydist::result_type distval = dist(eng); 
 
    distval = distval;  // to quiet "unused" warnings 
    engval = engval; 
 
    std::cout << "mean == " << dist.mean() << std::endl; 
    std::cout << "sigma == " << dist.sigma() << std::endl; 
 
    dist.reset(); // discard any cached values 
    std::cout << "a random value == " << dist(eng) << std::endl; 
    std::cout << "a random value == " << dist(eng) << std::endl; 
    std::cout << "a random value == " << dist(eng) << std::endl; 
 
    return (0); 
    }
