Exponent
Functions. To
specify
an exponent of
ten
while en
tering a number, use Q0. To
calculate
an exponent of ten (the base 10
antilogarithm), use
§§Q(E]
(chapter 4). To
calculate
the result of any
number raised to a power (exponentiation), use
[3

Understanding
Digit
Entry
As you key in a number, the
cursor
(_) appears in the display. The
cursor shows you where the next digit will go; it therefore indicates
that
this number is not completed yet. In technical talk, we say that
digit
entry
is not
terminated.

Description:

123.
Digit entry is
not
ter
minated:
the
number
is
not completed.
If you
execute
a
function
to calculate a
result,
then the cursor disap
pears because the number is complete. Digit entry has been
terminated.

Ialso terminates digit entry. This is why you must sep

two

with

I:
to
terminate
one
number
before
starting to key in the second one.

number.
If digit entry is not terminated (the cursor is present), then
(5
back
spaces to erase the last digit. If digit entry is terminated (no cursor),
then (T) acts like (c] and clears the entire number. Try it!
