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

k Conjugate Complex Numbers [OPTN]-[CPLX]-[Conj]
A complex number of the form
a + b i becomes a conjugate complex number of the form
a – b i .
