Extended integers seems to work on base ten thousand. On J8 64 bit I get 3!:3&.>1x;10000x;100000000x

For some reason copying and pasting from J likes to compress leading blanks.) Seems a bit wasteful of space, particularly on a 64 bit system, but it certainly speeds up converting to decimal output. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
