This is a relic of CF's refusal to understand integers. All numerics within CF are treated as floating point numbers (java.lang.Double). As such, integer arithmetic doesn't exist. Most of the time it's no big deal, and CF does some autocorrection when doing certain operations, but it can occasionally bite you.
