negative number raised to even power

[Dirk.]

Well, due to my home, I have to recommend Licher.
But anyway: One of the main points for me is the inconsistency. The calculator behaves differenty when processing a previously calculated result and when entering something leading to the same display. I think the way the algebraic SHARP-Calculators (SHARP EL-512S and SHARP EL-520V) behave is much more consistent.

... and now I'll go out for an Edinger Weißbier :-)
