+void \fBlibj2_not_j2u\fP(struct libj2_j2u *\fIa\fP);
+void \fBlibj2_not_j2u_to_j2u\fP(const struct libj2_j2u *\fIa\fP, struct libj2_j2u *\fIr\fP);

+
+.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 .
