CASIO CLASSWIZ fx-991EX

[Marcio]

If it is not too much to ask, please, evaluate the following with the 991EX to full 12-dig precision:

\[ARG(e^{\frac{\pi*i}{180\times1E7}}) \]

Not all calculators (including HPs) can get all digits correct: 9.999... E-8. In actuality, I have never seen any Casio do badly on tests like this, cheap calculators and many android emulators, OTOH, will fail horribly.

Thanks.

Marcio
