The highlighted expression or number is re-entered. If the

You can use the last result as the first expression in the edit
line without pressing
ANS . Pressing , , , or
, (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

on page 1-22 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.
