Try this:

Debug Pow(0,0)

It gives 1

And in Windows calculator too

Err, not sure, but I think it's the right answer.

Anything raised to the zero'th power is one.

I've tested this in other languages and they return 1, so it's not a bug.

Denmark, Canada, France ...

Oufffh! Finally a nice reply!! Thanx

However, that link talks about conventions, this is, needs depending on equations or math contexts interests.
0^0 is an error, and at least we need a valid result for that operation, in general it must be taken as ERROR while working with real numbers.

0^0 is an error? i never heard anyone complaining about it...
i never ever heard that you can choose yourself either! Tried 4 calculators on my computer, my programmable Texas instruments 84+ , and other normal calculators.

oh also asked my father who has been at university for 7 years, he is a canc. scient and he said nearly angry when i asked if 0^0 could be 0: "0^0 is DEFINED to be 1!". so i doubt that you can choose yourself..

again it isnt an error its just defined that anything no matter what powered in 0, is 1!

you can read that in any math book from any university or whatever you want. Looked it up in my own gymnasium mathbook: x^0 is defined to be 1.

so the answer is only 100% correct, if you can trust a cand.scient with highest math grade on university, a mathbook, 4 pc-calculators and a programmable graph-calculator.

so in general it shall NOT be taken as an error. If PB did that it would go against the law of maths lol then we could suspect it to let 2+2=5.. who knows??

Yes, thefool, yes, 0^0 is an error whenever we work with real values.
If you have never heard about it, then i can only understand you have never had a math teacher.

hmm sorry my math teacher is only an cand. scient datalog..
but whatever..
why is it an error? its NOT

i doubt my calc uses false numbers

TheFool is correct, the answer is 1.
