Thanks for that, I forgot how to do it and couldn't work it out.

I found another way which I'm scared to mention... it involved splitting
the 8 bits up into two halves getting their hex values and lots more
weirdness.  This way is much nicer, and faster too if you put the
results of pow in a dictionary.




Thanks again :)
