Errors
The calculator will display an error message whenever an error occurs for any reason during a calculation.
Displaying the Location of an Error
While an error message is displayed, pressing 
, 
, or 
returns to the screen that was displayed immediately before the error message appeared. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again.
Example: When you input 14 ÷ 0 × 2 by mistake instead of 14 ÷ 10 × 2.
- 14

Error Messages
Syntax ERROR
Cause:
There is a problem with the format of the calculation you are performing.
Action:
Make necessary corrections.
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).
While using an app that does not support complex numbers or while a screen that does not accept input of complex numbers is displayed, you attempted to execute a calculation that includes a variable where a complex number is stored.
When Verify is enabled (Verify ON) while using the Complex app, you entered an inequality that includes a complex number.
Action:
Check the input values, reduce the number of digits, and try again.
When using a variable as the argument of a function, make sure that the variable value is within the allowable range for the function.
To execute a calculation that includes a variable where a complex number is stored, while using an app that does not support complex numbers or while a screen that does not accept input of complex numbers is displayed, change the value stored to the variable to a real number.
You cannot use Verify in the Complex app to determine if an inequality that includes a complex number is true. You can determine the truth of an equation that includes a complex number.
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.
Argument ERROR
Cause:
There is a problem with the argument of the calculation you are performing.
Action:
Make necessary corrections.
Dimension ERROR (Vector app only)
Cause:
You are trying to perform a calculation with vectors whose dimensions do not allow that type of calculation.
Action:
Check the dimensions specified for the vectors to see if they are compatible with the calculation.
Range ERROR (Table app only)
Cause:
An attempt to generate a number table in the Table app whose conditions cause it to exceed the maximum number of allowable rows.
Action:
Narrow the table calculation range by changing the Start, End, and Step values, and try again.
Time Out (Distribution app only)
Cause:
The current distribution calculation ends without the ending condition being fulfilled.
Action:
Change the value of each parameter.
Circular ERROR (f(x) and g(x) feature only)
Cause:
Circular reference is occurring in a registered composite function ("Registering a Composite Function").
Action:
Do not have g(x) input into f(x), and f(x) input into g(x) at the same time.
No Operator (Calculate and Complex apps only)
Cause:
You entered an expression that does not include an operator and tried to determine if it is true.
Action:
Enter an equation or inequality and then determine if it is true.
Not Defined
Cause (f(x) and g(x) feature):
You attempted to calculate f(x) or g(x) with f(x)/g(x) undefined.
Action:
Define f(x) or g(x) before calculating f(x)/g(x).
Cause (Vector app):
The vector you are trying to use in a calculation was input without specifying its dimension.
Action:
Specify the dimension of the vector and then perform the calculation again.
