The **`llabs()` function** in C++ returns the absolute value of a long, long int data.

It is similar to the `abs()` and `labs()` functions except for the type of parameters.

# Standard library
```c++
#include<cstdlib>
```
# Syntax of llabs() function
```c++

long long int llabs(long long int n)
```

# Parameters

- `n` - represents the value whose absolute value is to be found

# Return value 

It returns the absolute value.

# Example 
    Input:
    n = -1234567890987654321

    Function call:
    llabs(n);

    Output:
    1234567890987654321














# Code





#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
	long long x,y;
	x = -1234567890987654321;
	y = 1234567890987654321;

	cout << "llabs(" << x << ")  = " << llabs(x) << endl;
	cout << "llabs(" << y << ")  = " << llabs(y) << endl;
	
	return 0;
}
