Calculation Stacks; Error Message And Error Locator - Canon F-718S User Manual

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 command stack has
128 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.
