I just wanted to check something. If I have a complex number of the form
[itex]a = C * \exp(i \phi) [/itex] where C is some noncomplex scalar constant. Then the phase of this complex number is simply [itex]\phi[/itex]. Is that correct?

If ##C < 0##, then you need to absorb the sign of ##C## into the phase: $$a = C\exp(i \phi) = C\exp(i(\phi + \pi))$$ If ##C = 0## then the phase is undefined.

Thank you for this detailed answer!
