Zero to the zeroth power

Not a Problem

GeoGebra evaluates 0^0 to 1, which is not correct, or at least there is no consensus on this. Moreover, when you try to raise zero to a negative power, the program just outputs infinity. 0^0 is evaluated to 1 in the Algebra and Spreadsheet view. In CAS, 0^0 just returns a question mark, so there's also a lack of consistency.


Was this intended to work like this?


Using GeoGebra 5.0.266.0

Yes, that's intended

In CAS:

0^0 returns a question markIsDefined(0^0) returns true

Why?

IsDefined() isn't implemented in the CAS (although by coincidence it will be for next release :) )
