Here we differ:
I expect that a documentation *fully* explains
a behaviour of a certain function (or something else),
not just some part of it.

It's not neccessary to know *how* things are coded but
the underlying idea and what the programmer can rely on.
The code can even differ from the documenation in case of bugs!
So what does it help to look into the code?

If a documenation satisfies the above requirement then
there is no need to look into the code *in any case*.
