Mistake on the Function Grapher page

I’ve just been looking at the Function Grapher and Calculator page:

http://www.mathsisfun.com/graph/function-grapher.php

And I noticed this:

floor Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer.

ceil Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer.

Should be the other way round!

Re: Mistake on the Function Grapher page

Oh yeah, should be:

floor Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer.

ceil Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer.

Right?

But maybe it could be said a lot easier than that.

Or:
ceil returns self if integer else returns integer closest proximity to the right on a number line.
floor returns self if integer else returns integer closest proximity to the left on a number line.
