Hmm..

Its really the +1s and +1+1s and *6+4 etc that I don't understand besides
this usually turns up a float value which is wierd considering the Yaroze is
a 32 bit integer machine and the value you get from this formula is always
FAR bigger that you actually need.

I don't think I'll ever figure this out :(
