k Absolute Value and Argument
[OPTN] - [COMPLEX] - [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 (
) for the complex
number 3 + 4
i
, with the angle unit set for degrees

• The result of the argument calculation differs in accordance with the current angle unit
setting (degrees, radians, grads).
