True, it will fail for all IPs in the 128.XXX.XXX.XXX range or higher. Worse
yet, the behavior changed from CF 4.0 to 4.5
I had several functions from a year ago that had to be hacked badly in order
to keep them working. The moral of the story? CF sucks giant rocks when it
comes to binary arithmetic.

Only problem is that formatbasen will fail if the number is to high. It
overloads what CF sees as an integer.
