Handling Error Or Overflow Conditions - Brother GeoBook NB-60 Getting Started Manual

Using the on-screen pointer
In addition to clicking buttons and selecting menu items, you can use the
on-screen pointer to edit the numbers in the Readout bar. You can select
digits in the display and move the insertion point. For instance, if you entered
the number 124, but meant to enter 14, you could drag across the 2 and press
BACKSPACE
to delete it..
Using the keyboard as a keypad
You may find it easier to use the keyboard for entering numbers. If you are
using the numeric keypad, be sure that the NUM LOCK key is on (the NUM
indicator is highlighted). Pressing NUM LOCK toggles the indicator between
on and off as does clicking the NUM LOCK button. The NtJM LOCK button
is located in the lower left comer of the screen.
Handling Error or Overflow Conditions
When the Calculator cannot perform a calculation, the word Overflow
appears in the Readout bar. This can happen if you try an operation not
allowed by the Calculator, such as dividing by zero. When Overflow appears,
clear it using one of the following methods:
• To clear an.error_
Click on the C/CE button to clear the number. This clears the error but retains
any operations in memory for the calculation in progress.
OR
Double-click on the C/CE button to clear the number and delete all previous
operations for the calculation in progress.
