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
