I read classpad forum and I see there a bug fixed in OS 3.04 that incorrect result appear when calculate e^(i*45) and I test this in OS 2.00.02 for fx-9860G but calculate incorrect too.
My test:
1-(degree mode):
e^(i*45)=0.525+0.850i==incorrect
2-(degree or radian mode):
e^(i*(pi/4))=0.707+0.707i==correct
Why give me incorrect result in test 1?

I think it isn't a bug. According to me the angle in the Euler's formula must be always set in radians.
edited: I wrote half of true only. There is a solution of it: Set the classpad in RAD and CPLX mode and write e^(i*45°). The important is the degree symbol.
I got these results:
TI-89 Titanium: 0.707+0.707i (in pretty print form), setting of cplx is not necessary
TI-Nspire CAS: 0.707+0.707i (in pretty print form), setting of cplx is not necessary
Casio Classpad 330 OS 3.04: 0.707+0.707i (in pretty print form), setting of cplx is necessary (if this cplx mode is not set, the warning box will appear. The message is: Non-Real in Calc.)
