PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       abs - return an integer absolute value
13

SYNOPSIS

15       #include <stdlib.h>
16
17       int abs(int i);
18
19

DESCRIPTION

21       The abs() function shall compute the absolute value of its integer  op‐
22       erand,  i.  If  the result cannot be represented, the behavior is unde‐
23       fined.
24

RETURN VALUE

26       The abs() function shall return the absolute value of its integer oper‐
27       and.

APPLICATION USAGE

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

RATIONALE

42       None.
