Absolute Value and Argument
[OPTN]
-
[CPLX]
-
[Abs]/[Arg]
The unit regards a complex number in the form
a
+
b
i
as a coordinate on a Gaussian plane,
and calculates absolute value
⎮
Z
⎮
and argument (arg).
Example
To calculate absolute value (
r
) and argument (
Ƨ
) for the complex number
3 + 4
i
, with the angle unit set for degrees
