Complex Number Calculations

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 (

) for the complex

number 3 + 4i, 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).
