Kstacks - Casio fx-270MS User Manual

k Stacks
This calculator uses memory areas, called "stacks," to tem-
porarily store values (numeric stack) and commands (com-
mand stack) according to their precedence during calcu-
lations. 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 is so com-
plex that the capacity of a stack is exceeded.
• Example:

• Calculations are performed in sequence according to
"Order of Operations." Commands and values are de-
leted from the stack as the calculation is performed.
