k Absolute Value and Argument [OPTN]-[CPLX]-[Abs]/[Arg]
The unit regards a complex number in the form a + bi as a coordinate on a Gaussian plane,
and calculates absolute value Z and argument (arg).
ExampleTo calculate absolute value (r) and argument ( θ ) for the complex
number 3 + 4i, with the angle unit set for degrees
AK3(CPLX)b(Abs)
(d+e!a(i))w
(Calculation of absolute value)
AK3(CPLX)c(Arg)
(d+e!a(i))w
(Calculation of argument)
# The result of the argument calculation differs
in accordance with the current angle unit
setting (degrees, radians, grads).
