Reverse Polish Notation (RPN)
The same entry-line editing tools are available in RPN mode as
in algebraic and textbook mode:
•
Press
C
to delete the character to the left of the cursor.
•
Press
SC
to delete the character to the right of the
cursor.
•
Press
J
to clear the entire entry line.
•
Press
SJ
to clear the entire entry line.
History in RPN mode
The results of your calculations are kept in history. This history is
displayed above the entry line (and by scrolling up to
calculations that are no longer immediately visible). The
calculator offers three histories: one for the CAS view and two for
Home view. CAS history is discussed in chapter 3. The two
histories in Home view are:
•
non-RPN: visible if you have chosen algebraic or textbook
as your preferred entry technique
•
RPN: visible only if you have chosen RPN as your preferred
entry technique. The RPN history is also called the
stack
. As
shown in the illustration below, each entry in the stack is
given a number. This is the stack level number.
As more calculations are added, an entry’s stack level number
increases.
If you switch from RPN to algebraic or textbook entry, your
history is not lost. It is just not visible. If you switch back to RPN,
your RPN history is redisplayed. Likewise, if you switch to RPN,
your non-RPN history is not lost.
When you are not in RPN mode, your history is ordered
chronologically: oldest calculations at the top, most recent at the
