.SH DESCRIPTION
The above listed functions calculate the
value absolute of the difference of the
values of
.I a
and
.I b
and stores the result in
.IR r ,
except the
.BR libj2_j2u_abs_diff_j2u ()
function, which stores the result in
.IR a .

The arguments are assumed to be
.RI non- NULL .

.SH RETURN VALUE
None

.SH ERRORS
The above listed functions cannot fail.
