If at all possible, I'd like to do this within an awk script, although I don't object to a system call in a pinch. Also, when I run your solution, I get:

Code:
# echo 1200,135.000000,12.30100,3212.3200,1.759403,1230,101.101010,100.000000 | sed "s/\.0\{1,\}//g"
1200,135,12.30100,3212.3200,1.759403,1230,101.101010,100

instead of:

Code:
1200,135,12.301,3212.32,1.759403,1230,101.101010,100

Do you get the same on your system, or does it work there?

FWIW, the most promising (but still failed...) solution I can think of is to put a trailing comma on $0, and then apply up to 5 times something like:

gsub("0,",",",$0)

Unfortunately, that only works if there's a way to apply it only to those fields which contain a decimal point. The fact that this is a gsub applying to $0 makes that difficult, and the solution as written would turn, for example, 1200 into 120, then into 12 on a second application.
