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 (
rθ) to input complex numbers. Complex number
calculation results are displayed in accordance with the complex number
format setting on the setup menu.

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°
θ180°. • Display of the calculation result while Linear Display
is selected will show
a and bi (or r and θ) on separate lines.
