Cheers Nick, I've grabbed your library, although now I've managed to
convert all my horrid maths into 6 IF statements....it's not as
accurate but it's bloody fast !

On a side note, would anyone be prepared to write a basic maths
tutorial ?  I would find this very useful as I haven't used any of my
maths for years and I've forgotten most of it.  At the moment I would
certainly find a reminder of basic geometry useful. I'm going out to
buy a book at the weekend.....

Richard.
