2-6 Complex Number Calculations
You can perform addition, subtraction, multiplication, division, parentheses calculations,
function calculations, and memory calculations with complex numbers just as you do with the
manual calculations described on pages 2-1-1 and 2-4-7.
You can select the complex number calculation mode by changing the Complex Mode item
on the Setup screen to one of the following settings.
•

•
{

When there is an imaginary number in
the argument, however, complex number
calculation is performed and the result is
displayed using rectangular form.
Examples:
ln 2
i
= 0.6931 1.570796327
i
ln 2
i
+ ln (– 2) = (Non-Real ERROR)
