C++ llabs() function

llabs() function is a library function of cstdlib header. It used to get the absolute of the given value. This function is similar to the abs() and labs() functions except for the type of the parameter, it is used for the long long integer values. It accepts a parameter and returns the absolute value.

Syntax of llabs() function:

C++11:

    long long int llabs (long long int n);

Parameter(s):

n – represents the value whose absolute value to found.

Return value:

The return type of this function is long long int, it returns the absolute value.

Example:

    Input:
    n = -1234567890987654321
    
    Function call:
    llabs(n);
    
    Output:
    1234567890987654321

    Input:
    n = 1234567890987654321
    
    Function call:
    llabs(n);
    
    Output:
    1234567890987654321

C++ code to demonstrate the example of llabs() function

// C++ code to demonstrate the example of
// llabs() function

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

// main() section
int main()
{
    long long int n;

    n = -1234567890987654321;
    cout << "llabs(" << n << "): " << llabs(n) << endl;

    n = 1234567890987654321;
    cout << "llabs(" << n << "): " << llabs(n) << endl;

    n = -1111222233334444555;
    cout << "llabs(" << n << "): " << llabs(n) << endl;

    n = 1111222233334444555;
    cout << "llabs(" << n << "): " << llabs(n) << endl;

    return 0;
}

Output

llabs(-1234567890987654321): 1234567890987654321
llabs(1234567890987654321): 1234567890987654321
llabs(-1111222233334444555): 1111222233334444555
llabs(1111222233334444555): 1111222233334444555
