uniform_real::uniform_real

Constructs the distribution.

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

Parameters

• min0
  The lower bound for random values.

• max0
  The upper bound for random values.

Remarks

Precondition: min0 < max0

The constructor constructs an object whose stored value stored_min holds the value min0 and whose stored value stored_max holds the value max0.

Example

// 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); 
    } 
 

min == 1
max == 2
a random value == 1.28517
a random value == 1.2238
a random value == 1.23248
