labs Arithmetic function in C programming language

We will learn this tutorial about labs Arithmetic function in C programming language

In the C Programming Language, the labs() is an arithmetic function, which returns the absolute value of a long integer

Declaration

Syntax

The syntax of  the labs() function in the C programming Language

long int labs(long int x);

parameters or Argument

x of the parameter or argument of this function for find absolute value of given long integer value

Return value

when passing a value for x, this function returns the absolute value of x

Required Header

In the C Language, the required header file for labs() function is

#include <math.h>

Example

Program 1

The following example explains the usage of fabc() function

#include <stdio.h>
#include <stdlib.h>

int main()
{
    long int a=659644L, b=-129888854L;
    printf("Absolute value of a : %ld\n",labs(a));
    printf("Absolute value of b : %ld\n",labs(b));
    getch();
    return 0;
}

 

When compile and run above program, this will produce the following result

absolute value of a:659644
absolute value of a:129888654

 

 

Program 2

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{
    long int m,n,o,p;//diclare of local  variable
    printf("Enter the long positive number\n");
    //get input positive
    scanf("%ld",&n);
    printf("Enter the long Negative number\n");
    //get input negative
    scanf("%ld",&o);
    m=labs(n);//assign absolute value of n to m
    p=labs(o);//assign absolute value of o to p
    printf("absolute value of the positive value is: %ld\n",m);
    printf("absolute value of the Negative value is: %ld",p);
//display labs values of given values
    getch();
    return 0;
}

When compile and run above program, this will produce the following result

Enter the long positive number
456783
Enter the long positive number
-542334
absolute value of te positive value is:456783
absolute value of the negative value is:542334
