k Absolute Value and Argument [OPTN] - [COMPLEX] - [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 ⎮ Z ⎮ 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

Real axis

AK3(COMPLEX) 2(Abs)

d+e1(

i ) w

(Calculation of absolute value)

AK3(COMPLEX) 3(Arg)

(d+e1(

i ) )w

(Calculation of argument)

• The result of the argument calculation differs in accordance with the current angle unit

setting (degrees, radians, grads).
