ratio_less_equal() function in C++

Last Updated : 09 Aug, 2021

The ratio_less_equal() is an inbuilt function in C++ which checks if the ratio R1 is less than or equal to the ratio R2. It returns True if the ratio is less than or equal to ratio 2, else it returns false.
Syntax:

template < class ratio1_name, class ratio2_name > ratio_less_equal

Template Parameters The function accepts two template parameters ratio1 and ratio2 which are to be compared.
Return value: The function returns a boolean value which is true if the ratio1 is less than or equal to the ratio2 otherwise returns false.
Below programs illustrates the above function:
Program 1:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// when both the ratios are equal
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
    typedef ratio<3, 9> ratio1;
    typedef ratio<1, 3> ratio2;

    // check if R1<=R2
    if (ratio_less_equal<ratio1, ratio2>::value)
        cout << "3/9 is less than or equal to 1/3";
    else
        cout << "3/9 is greater than 1/3";

    return 0;
}

Output:

3/9 is less than or equal to 1/3

Program 2:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// to show less than
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
    typedef ratio<1, 3> ratio1;
    typedef ratio<1, 2> ratio2;

    // check if R1<=R2
    if (ratio_less_equal<ratio1, ratio2>::value)
        cout << "1/3 is less than or equal to 1/2";
    else
        cout << "1/3 is greater than 1/2";

    return 0;
}

Output:

1/3 is less than or equal to 1/2

Program 3:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// to show when greater than
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
    typedef ratio<1, 8> ratio1;
    typedef ratio<1, 10> ratio2;

    // check if R1<=R2
    if (ratio_less_equal<ratio1, ratio2>::value)
        cout << "1/8 is less than or equal to 1/10";
    else
        cout << "1/8 is greater than 1/10";

    return 0;
}

Output:

1/8 is greater than 1/10
