I've the so called classpad 330 (with OS 3.03 installed). It annoys me some times in areas where my ti 89 titanium makes me happy.I'll post those annoyance later but first, here's the question:
What's the angle for the complex number −16+47i?
angle(-16 + 47i) enter...ans 108.79 degrees ..it also gives me the correct ans in radians.
angle(-16 + 47i) exe ans ERROR incorrect number of arguments.
What annoys me too is the fact that there's no example or explanation of some sort of this scenario on cp manual. What am I doing wrong on cp guys? What's missing in my cp entry?
Thank you all

Different from Ti89, CP's angle function is the function which return the angle formed by two vector.
you can also try angle([-16,47],[1,0])
