[Jprogramming] A Tale Without End

[Don Guinn]

Extended integers seems to work on base ten thousand. On J8 64 bit I get

   3!:3&.>1x;10000x;100000000x

(Had to add spaces to get the lines with blanks to line up. 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.
