in modes Remarks
DEC
DEC
r
\
Decrements
r
by one, equivalent to 1 STO
–
r
,
but without modifying the stack.
DECM
\
Sets default decimal mode for calculations.
DECOMP
…
FRC
Decomposes
x
(after converting it into an impro-
per fraction, if applicable), resulting in a stack
[
numerator(
x
), denominator(
x
),
y, z
] or
[
num(
x
), den(
x
),
y, z, t, a, b, c
] , respectively.
Reversible by division.
DEG
DECM
Sets angular mode to degrees.
DEG
…
DECM
Takes
x
as degrees and converts them to the
angular mode currently set.
DENANY
…
\
Sets default fraction format like in
HP-35S
, al-
lowing maximum precision. Any denominator up
to the value set by DENMAX may appear.
DENFAC
…
\
Sets ―factors of the maximum denominator‖.
With e.g. DENMAX = 60, possible denominators
are 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.
DENFIX
…
\
Sets fixed denominator format, i.e. the denomi-
nator equaling DENMAX always.
DENMAX
…
\
Works like
/
c in
HP-35S
, but maximum deno-
minator settable is 9999. It will be set to this val-
ue if
x
< 1 or
x
> 9999 at execution time. For
x
= 1 the current setting is recalled.
DET
…
\
Takes a
descriptor
of a square matrix in
X
and
returns the determinant of the matrix. The matrix
is not modified.
DISP
DISP
n
DECM
Changes the number of decimals shown while
keeping the basic display format (FIX, SCI,
ENG) as is. With ALL set, DISP will change the
switchover point (see ALL).
DROP
…
\
Drops
x
. See
above
for details and
C
DROP.
DSE
r
PRG
Given
cccccc.fffii
in
r
, DSE decrements
r
by
ii
, skipping next program line if then
ccccccc
≤
fff
. If
r
features no fractional part
then
fff
is 0 and
ii
is set to 1.
Note that neither
fff
nor
ii
can be negative,
and DSE makes only sense with
cccccc
> 0.
