The Calculator screen behaves exactly like any other
RPN-format calculator. It consists of a stack that can
contain any number of values and buttons that perform
various operations. When a value is being entered from
the keypad, it is displayed in a special area called the
active area. This value is then place in Level 1 of the
stack after tapping the Enter key.
Tapping a button on the display performs the
corresponding operation on either the last value in the
display, or the last two values, depending on the
operation. Each button is explained below where the
value in Level 1 is x and the value in Level 2 is y.
+: Adds x and y.
÷: Divides y by x.
−: Subtracts y from x.
×: Multiplies x and y.
↵: Moves the active value to Level 1 of the stack, or duplicates Level 1
if there is no active value.
Swap: Swaps positions of x and y in the stack.
Drop: Drops (removes) x from the stack.
Edit: Moves the value in Level 1 to the active area where it can be
edited.
±: Changes the sign of x.
1/x: Inverse of x.
