ratio_equal() in C++ with examples
The ratio_equal() is an inbuilt function in C++ STL that checks if two given ratios are equal or not.
Syntax:
template < class ratio1_name, class ratio2_name > ratio_equal
Template Parameters: The function accepts two template parameters ratio1 and ratio2 which are to be compared.
Return value: The function returns true if the ratios are equal otherwise it returns false.
Below programs illustrate the ratio_equal() function:
Program 1:
// C++ program to illustrate the // ratio_equal function #include <iostream> #include <ratio> using namespace std; int main() { typedef ratio<3, 9> ratio1; typedef ratio<1, 3> ratio2; // If both the ratios are same if (ratio_equal<ratio1, ratio2>::value) cout << "Both ratio are equal"; else cout << "Both ratio are not equal"; return 0; } |

Both ratio are equal
Program 2:
// C++ program to illustrate the // ratio_equal function #include <iostream> #include <ratio> using namespace std; int main() { typedef ratio<1, 2> ratio1; typedef ratio<5, 4> ratio2; // If both the ratios are same if (ratio_equal<ratio1, ratio2>::value) cout << "Both ratio are equal"; else cout << "Both ratio are not equal"; return 0; } |
