program steps backwards (1
≤
n
≤ 99).
So e.g. BACK 01 goes to the previous step.
Reaching step 000 stops program execution.
BASE
BASE
n
\
Sets the base for integer calculations, with
2
≤
n
≤ 16. Popular bases are directly accessible
on the keyboard. Current integer base setting is
indicated in the exponent as explained
above
.
Furthermore, BASE0 equals DECM, and BASE1
calls FRACT. See below.
ATTENTION:
Going from DECM to any integer
mode, the current stack contents will be trun-
cated. Going from integer to DECM, the current
stack contents will be converted. Other register
contents will not!

DECM
Measures the battery voltage in the range be-
tween 1.9V and 3.4V and returns this value.
Integer
As above but returns the voltage in 0.1V units.
