Mistake on the Function Grapher page
Ive 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.
