Example

See how | shift [/j/vs retrieves and reuses the last result (50),

and I ENTER I updates ANS (from 50 to 75 to 100).

You can use the last result as the first expression in the edit

line without pressing | shift\ans. Pressing (+], Q, fx], or

pT], (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 fflU. See “Using previous results” on page 1-

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 I ENTER I evaluates (or re-evaluates) the last input,

whereas pressing |sHlFT]/iA''y copies the last result (as ANS) into

the edit line.
