The ratio_less() is an inbuilt function in C++ which checks if the ratio R1 is less than the ratio R2. It returns True if the ratio is less than ratio 2, else it returns false.
Syntax:
template < class ratio1_name, class ratio2_name > ratio_less
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 ratio2 otherwise it returns false.
Below programs illustrates the above function:
Program 1:
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
typedef ratio<3, 9> ratio1;
typedef ratio<1, 3> ratio2;
if (ratio_less<ratio1, ratio2>::value)
cout << "3/9 is less than 1/3" ;
else
cout << "3/9 is not less than 1/3" ;
return 0;
}
|
Output:
3/9 is not less than 1/3
Program 2:
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
typedef ratio<1, 2> ratio1;
typedef ratio<4, 7> ratio2;
if (ratio_less<ratio1, ratio2>::value)
cout << "1/2 is less than 4/7" ;
else
cout << "1/2 is not less than 4/7" ;
return 0;
}
|
Output:
1/2 is less than 4/7
