Unless you convert from polar form* to Cartesian form:

Let's take "45e^(j * 44°)":

32.37029101523930127102246035055203587038080515238845970760... +
31.25962667065487789953828347402088034639160866937838052053... i

From <http://www.wolframalpha.com/input/?i=45*e^%2844%C2%B0i%29>.

* Which you are much more likely to encounter than the Cartesian form,
considering complex numbers are most useful when dealing with wave
forms.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
