DECM
Returns a forecast
x
for a given
y
(in
X
) follow-
ing the fit model chosen. See L.R. for more.
x !
DECM
Return the factorial, equaling
Γ(
x
+ 1) .
x
Interprets
x
as character code. Appends the re-
spective character to
alpha
, similar to XTOA in
HP-42S
.
x

\
Swaps the contents of
X
and
r
, in analogy to
x
y
.
x
y
\
Swaps
x
and
y
, performing Re
Im if a com-
plex operation was executed immediately be-
fore. See
above
for details.
x < … ?
x < ?
a
\
Compare
x
with
a
. E.g.
x < ?
will
compare
x
with the contents of register
K
, and
will be listed as
in a program. See the
examples given in the
addressing table above
for more.
x
≈ ? will be true if the rounded values of
x
and
a
are equal (see ROUND).

com-
pare the complex number

y
as explained
in the
addressing table above
.
The signed tests x = +0 ? and x =
–0 ? are
meant for integer modes 1COMPL and SIGNMT,
and for DECM if flag
D
is set. Then, e.g. 0 di-
vided by -7 will display -0.
