Scientifi c Function Calculations
Unless otherwise noted, the functions in this section can be used in any of the calculator's
calculation modes, except for the BASE-N Mode.
Scientifi c Function Calculation Precautions
• When performing a calculation that includes a built-in scientifi c function, it may take
some time before the calculation result appears. Do not perform any key operation on the
calculator until the calculation result appears.
• To interrupt an on-going calculation operation, press @ .
