Dear Roger, thanks
no care taken by me re rounding and truncation errors, that is part of the measure of J and the pocket pc to see how well they do on their own I know there is a nice integral as well, very quick. No clue how to do it in J yet. Repeating fractions don't do anything for me yet, if i have to feed in that much data, copy that many numbers, I might as well copy the constant digit for digit instead. I do see that J is slick doing it, yes. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
