PROLOG

NAME
       abs - return an integer absolute value

SYNOPSIS
       #include <stdlib.h>

       int abs(int i);

DESCRIPTION
       The abs() function shall compute the absolute value of its integer operand, i. If the result cannot be represented, the behavior  is  unde-
       fined.

RETURN VALUE
       The abs() function shall return the absolute value of its integer operand.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       In two's-complement representation, the absolute value of the negative integer with largest magnitude {INT_MIN} might not be representable.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
