.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 .
.PP
The arguments are assumed to be
.RI non- NULL .
.SH RETURN VALUE
None
.SH ERRORS
The above listed functions cannot fail.
.SH HISTORY
The
.BR libj2_j2u_abs_diff_j2u (),
.BR libj2_j2u_abs_diff_j2u_to_j2u (),
.BR libj2_j2i_abs_diff_j2i_to_j2u (),
.BR libj2_ju_abs_diff_ji_to_j2u (),
and
.BR libj2_ji_abs_diff_ju_to_j2u ()
functions were added in version 1.2 of
