But seriously, if you're not into your maths as part of your job or you have a pretty big interest in it, how is the question posed in this thread a "basic" one? Seems damn hard to me, frankly.
It's not basic if you bloody teach it... why else do you think I haven't answered?
Going to sit down and have a (google-aided) crack now, and see what I get.
