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 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:
// C++ program to illustrate the // ratio_less function #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<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:
// C++ program to illustrate the // ratio_less function #include <iostream> #include <ratio> using namespace std;
int main()
{ typedef ratio<1, 2> ratio1;
typedef ratio<4, 7> ratio2;
// check if R1<R2
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
