Say I want to compare 2 floaring point numbers, I have a number in st(7) and a number in st(0), I want to compate st(7)with st(0) and pop st(0), then jump if st(0) was greater than st(7).

So I should use fcomp, I've got that much, but then what, do I just use ja or is there a special thing I have to do?
