-.SH DESCRIPTION
-The
-.BR abs ()
-function computes the absolute value of the integer
-argument \fIj\fP.
-The
-.BR labs (),
-.BR llabs ()
-and
-.BR imaxabs ()
-functions compute the absolute value of the argument \fIj\fP of the
-appropriate integer type for the function.
-.SH RETURN VALUE
-Returns the absolute value of the integer argument, of the appropriate
-integer type for the function.
-.SH ATTRIBUTES
-.SS Multithreading (see pthreads(7))
-The
-.BR abs (),
-.BR labs (),
-.BR llabs (),
-and
-.BR imaxabs ()
-functions are thread-safe.
-.SH CONFORMING TO
-SVr4, POSIX.1-2001, 4.3BSD, C99.
-.\" POSIX.1 (1996 edition) requires only the
-.\" .BR abs ()
-.\" function.
-C89 only
-includes the
-.BR abs ()
-and
-.BR labs ()
-functions; the functions
-.BR llabs ()
-and
-.BR imaxabs ()
-were added in C99.
-.SH NOTES
-Trying to take the absolute value of the most negative integer
-is not defined.
-.PP
-The
-.BR llabs ()
-function is included in glibc since version 2.0.
-The
-.BR imaxabs ()
-function is included in
-glibc since version 2.1.1.
-.PP
-For
-.BR llabs ()
-to be declared, it may be necessary to define
-\fB_ISOC99_SOURCE\fP or \fB_ISOC9X_SOURCE\fP (depending on the
-version of glibc) before including any standard headers.
-.PP
-By default,
-GCC handles
-.BR abs (),
-.BR labs (),
-and (since GCC 3.0)
-.BR llabs ()
-and
-.BR imaxabs ()
-as built-in functions.
