Hi guys
Thanks very much for the replies..........all very useful, and added to my knowledge bank!
Yes, I did some pretty crude things in this sketch...........like overwriting the second decimal place with the measurement unit i.e. V so that it would look like it was displaying just one decimal place!!
Have modified my code, and although the results look the same as before...........I'm now safe in the knowledge that it is now done properly and will be future proof.
Thanks again
Steve
