Hi and thanks for the fast answer.

I tried to search the site, but "!!" or "not not" are not really good search terms Wink

So you cast int to bool with a "!"?
And then you return exctly the opposite?

So if the function returns 0 (which would be false in bool statement anyway, so why cast?) you convert it to bool, and then the second "!" returns true?
Is it right?

It's a bit confusing though Razz
