# isgreaterequal() in C/C++

The function isgreaterequal() is used to check that the first argument is greater than or equal to the second one. It is declared in “math.h” header file in C language. It returns true on success, otherwise false.

Here is the syntax of islessgreater() in C++ language,

bool isgreaterequal(value1 , value2);

Here,

value1 − This is the first argument which will be checked with value2.

value2 − This is the second argument which is used to check value1 that is greater or equal.

Here is an example of isgreaterequal() in C++ language,

## Example

Live Demo

#include<iostream>
#include<math.h>
using namespace std;
int main() {
int val1 = 28;
int val2 = 8;
bool result;
result = isgreaterequal(val1, val2);
cout << "val1 isgreaterequal than val2 : " << result << endl;
return 0;
}

## Output

val1 isgreaterequal than val2 : 1

In the above example, two values are compared and one of them is less or greater than the other. It checks value1>value2 || value1=value2. If one of them ( value1>value2 OR value1=value2 ) is true, it will return 1. Otherwise, it will return 0.

Now, let’s see another example when first value is less than second,

## Example

Live Demo

#include<iostream>
#include<math.h>
using namespace std;
int main() {
int val1 = 5;
int val2 = 8;
bool result;
result = isgreaterequal(val1, val2);
cout << "val1 isgreaterequal than val2 : " << result << endl;
return 0;
}

Here is the output,

## Output

val1 isgreaterequal than val2 : 0
