template ( class RealType, size_t bits, class URNG ) RealType generate_canonical (URNG& g);Template parameters: This template accepts three parameters as mentioned above and described below:
- RealType: The function returns a value of floating point type.
- bits: Maximum number of bits in the mantissa.
- URNG: A uniform random number generator class.
// C++ program to illustrate generate_canonical() // function. #include <bits/stdc++.h> using namespace std;
int main()
{ // Obtain a root from the system clock:
unsigned root = chrono::system_clock::now().time_since_epoch().count();
// Random number engine class
// that generates pseudo-random numbers
default_random_engine generator(root);
double can_val = generate_canonical< double ,
numeric_limits< double >::digits>(generator);
// Print the random canonical value
// It will display different value everytime
cout << "Random canonical value: " << can_val;
return 0;
