Complex Number Calculations
# 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

and argument (arg).
Example To calculate absolute value ( r ) and argument (Ƨ) for the complex
number 3 + 4 i , with the angle unit set for degrees
Imaginary axis

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 + b i becomes a conjugate complex number of the form
a – b i .
Example To calculate the conjugate complex number for the complex number 2
+ 4
i
