uniform_real::uniform_real

构造分发点对应。

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

参数

• min0
  随机值的下限。

• max0
  随机值的上限。

备注

前置条件: min0 < max0

构造函数构造存储值 stored_min 保存值 min0，并存储值 stored_max 表示值 max0的对象。

示例

// 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); 
    }
