uniform_real::uniform_real

建構散發。

explicit uniform_real(result_type min0 = result_type(0), result_type max0 = result_type(1));

參數

• min0
  選擇性值的下限。

• max0
  選擇性值的上限 (Upper Bound)。

備註

前置條件: min0 < max0

建構函式建構儲存值 stored_min 保留值 min0 ，並儲存值 stored_max 保留值 max0的物件。

範例

 

// std_tr1__random__uniform_real_construct.cpp 
// compile with: /EHsc 
#include <random> 
#include <iostream> 
 
typedef std::ranlux64_base_01 Myeng; 
typedef std::uniform_real<double> Myceng; 
int main() 
    { 
    Myeng eng; 
    Myceng ceng(1.0, 2.0); 
    Myceng::input_type engval = eng(); 
    Myceng::result_type compval = ceng(eng); 
 
    compval = compval;  // to quiet "unused" warnings 
    engval = engval; 
 
    std::cout << "min == " << ceng.min() << std::endl; 
    std::cout << "max == " << ceng.max() << std::endl; 
 
    ceng.reset(); // discard any cached values 
    std::cout << "a random value == " << ceng(eng) << std::endl; 
    std::cout << "a random value == " << ceng(eng) << std::endl; 
    std::cout << "a random value == " << ceng(eng) << std::endl; 
 
    return (0); 
    }
