DESCRIPTION

llabs returns the absolute value of a long long int .

RETURN VALUE

llabs returns the absolute value of its argument. Both the result and the argument are of long long int type.

IMPLEMENTATION

llabs is implemented as a macro that invokes the built-in abs function.

EXAMPLE

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

main()
{
   long long int a, c;  /* The variable, a, can have a negative value. */
   int b;
   puts("Enter values for a (can be negative) and b:");
   scanf("%ld %d", &  a, &  b);

   c = llabs(a*b);  /* Calculate absolute value.                   */

   printf("The absolute value of their product = %ld\n", c ); }
}
