.SH DESCRIPTION
The above listed functions calculate
the bitwise inverse (NOT) of
.IR a .
For the
.BR libj2_not_j2u ()
function, the result is stored in
.IR a.
For the
.BR libj2_not_j2u_to_j2u ()
and
.BR libj2_not_ju_to_j2u ()
functions, the result is stored in
.IR r.
Additionally, for the
.BR libj2_not_ju_to_j2u ()
.I a
is virtually extended to double-max precision,
so all bits in the most significant half of
.I r
will always be set.
.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_not_j2u (),
.BR libj2_not_j2u_to_j2u (),
and
.BR libj2_not_ju_to_j2u ()
functions were added in version 1.0 of
.BR libj2 .
