    ceil(0.000001) = 1
    ceil(0) =... 0? Wtf?
But that's a perfectly well defined function. Not every function has to be continuous.

In the first place, not every function has to be defined everywhere.

Well, if 1/x -> infinity as x -> 0, x > 0, and 1/x -> -infinity as x -> 0, x < 0, then the average of +infinity and -infinity is zero. :-)
