Unfortunately, the code did not do the whole job. E.g.: (format #f "~4,2F" 23.45678) -> "23.4" ;; expected "23.46" (format #f "~6,3F" 3/17) -> " 22/12" ;; expected " 0.176" (format #f "~6,3F" (sqrt -3.9)) -> " 0.000" ;; expected something more like "0.0+1.975i" ? (format #f "~4,2F" 32) -> "3200" ;; expected "32.00" Note tha CL defines ~F for non-numeric arguments: [CL] (format nil "~6,2F" "foo") -> " foo" I am willing to do the work, but I suspect that handling such cases would make the code larger--and cons more. It _is_ a slippery slope. Perhaps a snoboard? 8^) Cheers, -KenD
