1-22 Getting started
Example See how >6+,)7@ANS retrieves and reuses the last result (50),
and >(17(5@ updates
ANS (from 50 to 75 to 100).
50>(17(5@ >@25
>(17(5@>(17(5@
You can use the last result as the first expression in the edit
line without pressing >6+,)7@
ANS. Pressing >@, >@, >;@, or
>j@, (or other operators that require a preceding argument)
automatically enters ANS before the operator.
You can reuse any other expression or value in the HOME
display by highlighting the expression (using the arrow keys),
then pressing
&23<a . See “Using previous results” on page 1-
21 for more details.
The variable
ANS is different from the numbers in HOME’s
display history. A value in
ANS is stored internally with the full
precision of the calculated result, whereas the displayed
numbers match the display mode.
HINT When you retrieve a number from ANS, you obtain the result
to its full precision. When you retrieve a number from the
HOME’s display history, you obtain exactly what was
displayed.
Pressing >(17(5@ evaluates (or re-evaluates) the last input,
whereas pressing >6+, )7@
ANS copies the last result (as ANS) into
the edit line.
