k Absolute Value and Argument
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 (
θ
) for the complex
number 3 + 4i, with the angle unit set for degrees
AK3(CPLX)2(Abs)
(d+e1(i))w
(Calculation of absolute value)
AK3(CPLX)3(Arg)
(d+e1(
i))w
(Calculation of argument)
The result of the argument calculation differs in accordance with the current an-
gle unit setting (degrees, radians, grads).
