Using Calculation Modes
Complex Number Calculations
(CMPLX)
To perform complex number calculations, first press
(CMPLX) to
enter the CMPLX Mode.
You can use either rectangular coordinates (
a
+
bi
) or polar coordinates
(
r
∠
θ
) to input complex numbers.
Complex number calculation results are displayed in accordance with the
complex number format setting on the setup menu.
Example 1:
(2 + 6
i
) ÷ (2
i
) = 3 -
i
(Complex number format:

Note
• If you are planning to perform input and display of the calculation result in polar
coordinate format, specify the angle unit before starting the calculation.
• The
θ
value of the calculation result is displayed in the range of -180° <
θ
≦
180°.
• Display of the calculation result while Linear Display is selected will show
a
and
bi
(or
r
and
θ
) on separate lines.
