So, usually there is no need to convert anything.

Ah, good.

Just after the section "Mathematical Functions", the manual says this:
   "Unless stated otherwise, all functions in this library operate with and
    return floating-point numbers."

In that case it would probably be useful to retouch the description of math.floor (etc.) to avoid them being interpreted as returning an integer:

  Returns the largest integer smaller than or equal to x.

(yes, it doesn't say "as an integer number" but the "integer" word in the above sentence could be confusing.)

Right, missed that :-)
