abs
ABS(3) Linux Programmer's Manual ABS(3)NAME
abs, labs, llabs, imaxabs - compute the absolute value of an integer
SYNOPSIS
#include <stdlib.h>
int abs(int j);
long int labs(long int j);
long long int llabs(long long int j);
#include <inttypes.h>
intmax_t imaxabs(intmax_t j);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
llabs():
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
DESCRIPTION
The abs() function computes the absolute value of the integer argument j. The labs(), llabs() and imaxabs() functions compute the absolute
value of the argument j of the appropriate integer type for the function.
RETURN VALUE
Returns the absolute value of the integer argument, of the appropriate integer type for the function.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99, SVr4, 4.3BSD. C89 only includes the abs() and labs() functions; the functions llabs() and imaxabs() were
added in C99.
NOTES
Trying to take the absolute value of the most negative integer is not defined.
The llabs() function is included in glibc since version 2.0. The imaxabs() function is included in glibc since version 2.1.1.
For llabs() to be declared, it may be necessary to define _ISOC99_SOURCE or _ISOC9X_SOURCE (depending on the version of glibc) before
including any standard headers.
By default, GCC handles abs(), labs(), and (since GCC 3.0) llabs() and imaxabs() as built-in functions.
