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 undefined.

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.
