Absolute Value and Argument
[OPTN]
-
[CPLX]
-
[Abs]
/
[Arg]
The unit regards a complex number in the format Z =
a
+
bi
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
