Ratio_less_equal function in C++
Given is the task to show the working of ratio_less_equal () function in c++.
The given function Ratio_less_equal checks if the value of ratio1 is less or equal than ratio2. It returns a Boolean constant “value” which returns true if ratio1 is less or equal than ratio2 else returns false.
Syntax
template ratio_less_equal
Parameters
This function accepts two template parameters one is ratio1 and another one is ratio2 which are to be compared.
Explanation of this function
In this function, if the value of ratio1 is less than or equal to the value of ratio2 then this function will return the Boolean value which is true i.e. integer digit 1 otherwise it will return false i.e. integer digit 0.
For Example
Input: 1/3 and 3/9 Output: 1/3 is less than or equal to 3/9. Input: 1/4 and 1/4 Output: 1/4 is equal to 1/4.
Approach that we are using in the below program
first we declare the two ratios.
Then assign the values of two ratios.
Then we check if the value of ratio1 is less than or equal to value of ratio2.
Using ratio_less_equal we can check that
Example
// C++ code demonstrate the working of ratio_less_equal
#include<iostream.h>
#include<ratio.h>
Using namespace std;
Int main( ){
typedef ratio<1, 3> ratio1;
typedef ratio<3, 9> ratio2;
if(ratio_less_equal<ratio1, ratio2>: : value)
cout<< “ ratio1 is less than or equal to ratio2”;
else
cout<< “ ratio1 is not less than or equal to ratio2”;
return 0;
}Output
If we run the above code it will generate the following output.
1/3 is less than or equal to 3/9. 4/16 is not less than or equal to 1/4.
