50g - Exponent of zero

[BarryT]

Question.
. By XPON, are we talking about using zero as an exponent, as in x^y, where y is the exponent and x<>0 ... or, are we talking E\EEX, as in x*10^y? Or are we talking about something entirely different?

Mathematically, the answer should be 1 in the first case, and x in the second? Soooo, I must be missing something? Does XPON mean something completely different? Now then... it is 2:30 in the morning here, so maybe I'm having a brain fart and just really need to get some sleep??

Interesting note: On my 32sii, 15c, 41cv, and two different Casios... 0^0 correctly gives an error. However, on my 48sx, 48gx, and according to a 42 emulator, 0^0 incorrectly returns an answer of 1.
