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
E
evaluates (or re-evaluates) the last
input,
whereas pressing
S
ANS
copies the last result (as
ANS
)
into the edit line.
Copy and paste
In addition to the COPY menu key that lets you copy
expressions from the Home view, there is a more
universal copy and paste clipboard that you can use. You
can highlight the value or expression you want in most
fields or the Home view history (e.g. F1(x) in the Function
App) and then paste it into the edit line or into another
compatible field. To copy a value or expression to the
clipboard, press
Sl
. To open the clipboard to
select and paste a value or expression,
press
Sm
.
Storing a value
in a variable
You can save an answer in a variable and use the

available for storing real values. These are
A
to
Z
and
θ
.
See the chapter
Variables and memory management
