Calculation results are rounded off to the specifi ed n umber of digits.
E-10 k Clearing the Calculation Mode and Setup Settings P erform the procedure described below to clear the current calculation mode and all setup settings and initialize the calculator to the f ollowing. Calculation Mode .............................
E-11 A Omitting the Multiplication Sign Y ou can omit the multiplication sign in the following cases. • Immediately before an open parenthesis: 2 × (5 + 4) • Immediately before a scientifi c fun.
E-12 k Editing a Calculation A Insert Mode and Overwrite Mode The calculator has two input modes. The inser t mode inser ts your input at the cursor location, shifting anything to the right of the cursor to make room. The o verwrite mode replaces the ke y operation at the cursor location with your input.
E-13 ddd D A Editing a Ke y Operation within an Expression With the inser t mode, use d and e to mov e the cursor to the right of the key operation you want to edit, press D to delete it, and then perform the correct ke y operation.
E-14 d 1 w • Instead of pressing e or d while an error message is display ed to fi nd the location of the error , you could also press A to clear the calculation. Basic Calculations Unless otherwise noted, the calculations in this section can be performed in any of the calculator’ s calculation mode, e xcept for the BASE Mode .
