Errors And Calculation Ranges - Sharp EL-738 Operation Manual

Errors and Calculation Ranges

Errors
An error will occur if an operation exceeds the calculation rang-
es, 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 oc-
curred. Edit the equation or press s to clear the equation.
Note: If an error occurs during the automatic calculation of a
listed fi nancial variable, pressing s , g , or y
displays the fi rst variable in the function.
