I'm afraid there's a logic flaw in the format determination in above posts: if the field in question contains ANY non-numeric character, use "%s" else use "%f" with an adaptable width. So, the (var ~ /[[:digit:]]/) doesn't lead nowhere - although it doesn't hurt, either, in above constellations. Had you reversed the sequence of the two tests, the "n3d5" field would have received the wrong format string.
