Down/up ratio calculation incorrect

[lisa-lthorrold]

if(this.forward.size() > 0){ return (double)(this.backward.size()/this.forward.size()); } return 0; }

This is casting the result of an integer division (int/int) [which returns an int] to a float, rather than correctly casting the numerator to force a double to ensure a proper division. The result is that the down/up ratio is always 0 or 1, which I think is unintended (based on the return type).
