I believe that this is the exact issue. ColdFusion runs on top of Java in which I can replicate the issue. This doesn't happen in PHP using the floor function. Hi Jean, thanks for this.

To find out try to print (6.84/45.60) * 100 - 15. If this returns something like 1.333e-15 there is a floating point rounding error (http://en.wikipedia.org/wiki/Round-off_error).
