In addressing, progress is recorded as explained in the
tables above
in detail. You
may cancel such pending operations by

5. In
programming mode
, the numeric display indicates the program step (000
– 505)
in the mantissa and the number of free steps in the exponent, while the dot matrix
shows the command contained in the respective step, e.g.:
6. For
floating point decimal numbers
, the mantissa will be displayed adjusted to the
right, the exponent to the left. Within the mantissa, either points or commas may be
selected as radix marks
17
, and additional marks may be chosen to separate thou-
sands. Assume the display set to FIX 4, then 12.345678901 millions may look like:
or
with thousands separators on, and without them like:
or
These separators may also be beneficial in integer or fraction modes described be-
low.
– With ENG 3 and after changing the sign, the same number will look like this:
or
If the last operation executed was a complex one, a capital
C
is displayed top left in
the dot matrix pointing to the fact that you find the result of this function in
X
and
Y
.
Floating point decimal numbers within
may be entered easily.
Using a decimal mantissa, even numbers down to 10
–394
can be keyed in. The calcu-
lator works with numbers down to 10
–398
correctly. Smaller values are set to zero.
For results
, error 4 or 5 will appear (see
below
).
7. In
integer modes
, numbers are displayed adjusted to the right as well. Word size
and complement setting are indicated in the dot matrix using a format
xx.ww
, with
xx
being
1c
or
2c
for 1‘s or 2‘s complement, respectively,
un
for unsigned, or
sm
for
sign-and-mantissa mode. Sign and first
digit of the exponent show the base, a ―c‖ in
the second
digit signals a carry bit set, an ―o‖ in the third an overflow. Integer bases
are indicated as follows:

Starting here, decimal input is written using a point as radix mark throughout this manual, although sig-
nificantly less visible, unless specified otherwise explicitly. By experience, the „comma people― are more
capable to read radix points and interpret them correctly than vice versa.
