Calculation Error
An error message dialog box, like the one shown below, appears when there is a problem 
with the syntax of an input expression or value, when the number of decimal places of a 
calculation result in the Standard mode (page 2-2-6) exceeds a specified range, etc. Tap [OK] 
to close the dialog box and return to the calculation.
Tip
•  The text of the error message dialog box depends on the type of error that occurred. For details, 
see the “Error Message Table” on page 
-5-1. 
•  If you perform a calculation that is mathematically undefined (such as division by zero), the 
message “Undefined” appears in place of the calculation result, without display of an error 
message.
