Ah, good.

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 :-)
