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
