Before Assuming Malfunction Of The Calculator - Casio FX-55 PLUS User Manual

Error Messages
Math ERROR
Cause: • The intermediate or final result of the calculation you are performing
exceeds the allowable calculation range. • Your input exceeds the allowable
input range (particularly when using functions). • The calculation you are
performing contains an illegal mathematical operation (such as division
by zero).
Action: • Check the input values, reduce the number of digits, and try again.
• When using independent memory as the argument of a function, make sure
that the memory value is within the allowable range for the function.
Stack ERROR
Cause: The calculation you are performing has caused the capacity of the
numeric stack or the command stack to be exceeded.
Action: • Simplify the calculation expression so it does not exceed the
capacity of the stack. • Try splitting the calculation into two or more parts.
Syntax ERROR
Cause: There is a problem with the format of the calculation you are
performing.
Action: Make necessary corrections.
Argument ERROR
Cause: A non-integer argument was input for the random number function
(RanInt#). Attempting to simplify a non-fraction value ('Simp).
Action: Input only integers for the argument (RanInt#). Input only fractions
for the argument ('Simp).
Can't Simplify
Cause: Attempting to simplify a fraction using a divisor that cannot be
simplified.
Action: Input a divisor that can be simplified.
Before Assuming Malfunction of the
Calculator...
Perform the following steps whenever an error occurs during a calculation
or when calculation results are not what you expected. If one step does not
correct the problem, move on to the next step.
Note that you should make separate copies of important data before
performing these steps.
1. Check the calculation expression to make sure that it does not contain any
errors.
2. If the above steps do not correct your problem, press the O key. This will
cause the calculator to perform a routine that checks whether calculation
functions are operating correctly. If the calculator discovers any abnormality,
it automatically clears memory contents. For details about initialized
settings, see "Configuring the Calculator Setup".
3. Initialize all settings by performing the following operation: r1(Setup)
=(Yes).
