The islessgreater fuinction determines whether the value of first argument is less than or greater than the value of second argument. If the value of first argument is less than or greater than the second argument then it returns 1 otherwise 0.
Note: If one or both the arguments are NAN, then the function returns false(0).
Syntax
Consider two numbers 'x' and 'y'. Syntax would be:
bool islessgreater(float x, float y);
bool islessgreater(double x, double y);
bool islessgreater(long double x, long double y);
bool islessgreater(Arithmetic x, Arithmetic y);
Parameter
(x,y) : The values which we want to compare.
Return value
| Parameter | Return value |
|---|---|
| x>y or x | 1 |
| x=y or x=nan or y=nan | 0 |
Example 1
Let's see a simple example when both x and y are equal.
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float x=1.2;
float y=1.2;
cout<<"Values of x and y are : "<<x<<","<<y<<'\n';
cout<<"islessgreater(x,y) : "<<islessgreater(x,y);
return 0;
}
Output:
Values of x and y are : 1.2,1.2
islessgreater(x,y) : 0
In this example, the values of both x and y are equal. Therefore, the function returns 0.
Example 2
Let's see a simple example when both x and y are of different type and are unequal.
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
int x=7;
float y=3.2;
cout<<"Values of x and y are : "<<x<<","<<y<<'\n';
cout<<"islessgreater(x,y) : "<<islessgreater(x,y);
return 0;
}
Output:
Values of x and y are : 7,3.2
islessgreater(x,y) : 1
In this example, value of x is greater than the value of y. Therefore, the function returns 1.
Example 3
Let's see a simple example when the value of x is NAN.
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float x=0.0/0.0;
float y=3.2;
cout<<"Values of x and y are : "<<x<<","<<y<<'\n';
cout<<"islessgreater(x,y) : "<<islessgreater(x,y);
return 0;
}
Output:
Values of x and y are : nan,3.2
islessgreater(x,y) : 0
In this example, value of x is NAN. Therefore, the function returns 0.
