abs, labs, llabs, imaxabs

Defined in header <stdlib.h> 
int        abs( int n );
-		 
long       labs( long n );
-		 
long long llabs( long long n );
-		 (since C99)
Defined in header <inttypes.h> 
intmax_t imaxabs( intmax_t n );
-		 (since C99)

Computes the absolute value of an integer number. The behavior is undefined if the result cannot be represented by the return type.

-

Parameters

- -
n - integer value

Return value

The absolute value of n (i.e. |n|), if it is representable.

-

Notes

In 2's complement systems, the absolute value of the most-negative value is out of range, e.g. for 32-bit 2's complement type int, INT_MIN is -2147483648, but the would-be result 2147483648 is greater than INT_MAX, which is 2147483647.

-

Example

#include <stdio.h>
-#include <stdlib.h>
-#include <limits.h>
- 
-int main(void)
-{
-    printf("abs(+3) = %d\n", abs(+3));
-    printf("abs(-3) = %d\n", abs(-3));
- 
-//  printf("%+d\n", abs(INT_MIN)); // undefined behavior on 2's complement systems
-}

Output:

-
abs(+3) = 3
-abs(-3) = 3
