k Absolute Value/Argument Calculation
• The procedure described below can be used to deter-
mine the absolute value (Abs) and argument (arg) for a
complex number of the format Z =
a + bi, which is pre-
sumed to exist as coordinates on a Gaussian plane.
• Example: To obtain the absolute value (
r) and argu-
ment (
θ
) for the complex number 3 + 4i, when DEG is
set for the angle unit mode
