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

α

-10-1.

• 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.
