Errors and Calculation Ranges Errors An error will occur if an operation exceeds the calculation ranges, or if a mathematically illegal operation is attempted. When an error occurs, pressing g or y automatically moves the cursor back to the place in the equation where the error occurred. Edit the equation or press s to clear the equation. Note: If an error occurs during the automatic calculation of a listed financial variable, pressing s, g, or y displays the first variable in the function.
