Unfortunately I don't understand the text in the code, so I don't have any idea what to expect out of it.

But I assume the return 0, 1 or 2 in the `giaiPT` function is used to signal the caller about the value range of <delta>. I don't know anything more than that : )

Answer 2

Can you share a link to that code where you saw `return 2 vv`?

Also it would be nice if you can specify which language in your question tag 👍
