INPUT RANGE AND ERROR MESSAGE
Calculation Stacks
This calculator uses memory areas, called "stacks", to
temporarily store numeric value (numbers) and
commands (+ – x ...) according to their precedence
during calculations.
The numeric stack has 10 levels and the command stack
has 24 levels. A stack error [Stack ERROR] occurs
whenever you try to perform a calculation that exceeds
the capacity of stacks.
Calculations are performed in sequence according to
"Order of Operations". After the calculation is performed,
the stored stack values will be released.
Calculation Accuracy, Input Ranges
Order of Operations
In the same precedence level, calculations are
performed from left to right.
Operation enclosed within paredtheses is performed
first. When a calculation contains an argument that is a
negative number, the negative number must be
enclosed within parentheses.
