Complex Number Calculations
k k k k k Absolute Value and Argument
[OPTN]-[CPLX]-[Abs]/[Arg]
The unit regards a complex number in the format Z = 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 + 4
i , 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).
