Question about chunk positions

[orzelek]

I'm looking at docs for those two functions:

is_chunk_generated(position) → boolean
Is a given chunk generated?

Parameters
position :: Position: The chunk's position.
request_to_generate_chunks(position, radius)
Request that the game's map generator generate chunks at the given position for the given radius on this surface.

Parameters
position :: Position: Where to generate the new chunks.
radius :: uint: Radius from position to generate new chunks in.

I have a question - how I should send positions to those functions?
Do they take tile coordinates and convert them to chunks or they need chunk based coordinates?

I've only dabbled with chunks but from what I've tried so far it seems you just send a normal position and the game works out which chunk it's in.
