k Inputting Complex Numbers
• In the CMPLX Mode, the W key changes function to become an
imaginary number i input key. In this section, the W key is referred
to as the i key. Use the i key when inputting a complex number
of the format a + bi. The key operation below shows how to input 2
+ 3i, for example.
2+3i

•You can also input complex numbers using polar coordinate format
(r ∠
θ
). The key operation below shows how to input 5 ∠ 30, for
example.
51y(∠)30

• The angle unit for argument
θ
input and result display is the
calculator’s default angle unit.
k Calculation Result Display Format
Your calculator can display complex number calculation results in
rectangular coordinate or polar coordinate format. You can select
the coordinate format by configuring the calculator’s setup. For more
information, see “Specifying the Complex Number Display Format”.
Examples of Calculation Results Using Rectangular
Coordinate Format (a + bi
)
Example 1: 2 × ('3 + i
) = 2'3 + 2i = 3.464101615 + 2i

•With Linear format, the real part and imaginary part are shown in
two different lines.
Example 2: '2 ∠ 45 = 1 + i (Angle Unit: Deg)
