Steve just told you that he doesn't need a number, he needs a whole 
number (an integer), and that this represents a more complex process 
that includes a call to int.

Why do you dismiss that and say there is no need to call int when you 
don't know the process involved?

It *may* be that Steve could use math.floor() or math.ceil() instead, 
neither of which have the same meaning as calling int(). But more likely 
he DOES need to convert it by calling int, just as he says.

Telling people that they don't understand their own code when you don't 
know their code is not very productive.
