Math Islessgreater Function

The islessgreater function checks if the value of the first parameter is either less than or greater than the value of the second parameter. It will return 1 if the first parameter is less than or greater than the second parameter; otherwise, it will return 0.

Note: If one or both the arguments are NAN, then the function returns false(0).

Syntax

Consider a pair of numerical values denoted as 'x' and 'y'. The syntax is as follows:

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

Example 1

Let's examine a basic scenario where both variables x and y hold the same value.

#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 instance, the values of x and y are identical. As a result, the function will output 0.

Example 2

Let's consider a basic scenario where both variables x and y are of distinct data types and have different values.

#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 instance, the value assigned to x surpasses the value assigned to y. As a result, the function yields a return value of 1.

Example 3

Let's consider a basic scenario where 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 instance, the value of x is not a number (NAN). As a result, the function will output 0.
