Ratio Manipulations in C++ | Set 2 (Comparison)

Manipulating ratio arithmetic has been discussed in Set 1 below

Ratio Manipulations in C++ | Set 1(Arithmetic)

In this article comparison of rations is discussed.

1. ratio_equal :- This templete alias checks if the ratios in its arguments are equal. Returns true if equal, else returns false. It returns a boolean member constant “value”.

1. ratio_not_equal :- This templete alias checks if the ratios in its arguments are not equal. Returns true if not equal, else if equal returns false. It returns a boolean member constant “value”.

// C++ code to demonstrate the working of
// ratio_equal and ratio_not_equal
#include<iostream>
#include<ratio> // for ratio manipulation
using namespace std;
int main()
{
    // Declaring ratios 
    typedef ratio<10, 100> ratio1;
    typedef ratio<1, 10> ratio2;
    
    // Checking if ratios are equal using ratio_equal
    ratio_equal<ratio1, ratio2>::value ? 
              cout << "Ratios are equal" :
              cout << "Ratios are not equal";
    cout << endl;
     
     // Checking if ratios are not equal using ratio_not_equal
    ratio_not_equal<ratio1, ratio2>::value ? 
               cout << "Ratios are not equal" :
               cout << "Ratios are equal";
    
    return 0;
    
}

Output:

Ratios are equal
Ratios are equal

3. ratio_greater :- This temporary alias check if ratio1 is greater than ratio2. It returns a boolean member constant “value” which returns true if ratio1 is greater than ratio2 else returns false.

4. ratio_less :- This temporary alias check if ratio1 is less than ratio2. It returns a boolean member constant “value” which returns true if ratio1 is less than ratio2 else returns false.

// C++ code to demonstrate the working of
// ratio_greater and ratio_less
#include<iostream>
#include<ratio> // for ratio manipulation
using namespace std;
int main()
{
    // Declaring ratios 
    typedef ratio<10, 100> ratio1;
    typedef ratio<11, 100> ratio2;
    
    // Checking if ratio1 is greater than ratio2 
    // using ratio_greater
    ratio_greater<ratio1, ratio2>::value ? 
             cout << "ratio1 is greater than ratio2" :
             cout << "ratio1 is not greater than ratio2";
    cout << endl;
     
    // Checking if ratio1 is less than ratio2 
    // using ratio_less
    ratio_less<ratio1, ratio2>::value ? 
             cout << "ratio1 is less than ratio2" :
             cout << "ratio1 is not less than ratio2";
    cout << endl;
    
    return 0;
    
}

Output:

ratio1 is not greater than ratio2
ratio1 is less than ratio2

5. ratio_greater_equal :- This temporary alias check if ratio1 is greater or equal than ratio2. It returns a boolean member constant “value” which returns true if ratio1 is greater or equal than ratio2 else returns false.

6. ratio_less_equal :- This temporary alias check if ratio1 is less or equal than ratio2. It returns a boolean member constant “value” which returns true if ratio1 is less or equal than ratio2 else returns false.

// C++ code to demonstrate the working of
// ratio_greater_equal and ratio_less_equal
#include<iostream>
#include<ratio> // for ratio manipulation
using namespace std;
int main()
{
    // Declaring ratios 
    typedef ratio<10, 100> ratio1;
    typedef ratio<1, 10> ratio2;
    
    // Checking if ratio1 is greater or equal than ratio2 
    // using ratio_greater_equal
    ratio_greater_equal<ratio1, ratio2>::value ? 
           cout << "ratio1 is greater or equal than ratio2" :
           cout << "ratio1 is not greater or equal than ratio2";
    cout << endl;
     
    // Checking if ratio1 is less or equal than ratio2 
    // using ratio_less_equal 
    ratio_less_equal<ratio1, ratio2>::value ? 
           cout << "ratio1 is less or equal than ratio2" :
           cout << "ratio1 is not less or equal than ratio2";
    cout << endl;
    
    return 0;
    
}

Output:

ratio1 is greater or equal than ratio2
ratio1 is less or equal than ratio2
