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
8PQ`— . 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.
H I N T 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.
