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).
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)

k Conjugate Complex Numbers [OPTN]-[CPLX]-[Conj]
A complex number of the form a + bi becomes a conjugate complex number of the form
a – bi.
Example To calculate the conjugate complex number for the complex number 2
+ 4i
AK3(CPLX)4(Conj)
(c+e1(i))w
# The result of the argument calculation differs
in accordance with the current angle unit
setting (degrees, radians, grads).
