Removing trailing zeroes
So, I can't figure out how to do a previous question with printf, so I'm taking a different approach. Suppose I have a set of numbers:

Code:
1200,135.000000,12.30100,3212.3200,1.759403,,1230,101.101010,100.000000

I want to remove all trailing zeroes after the decimal, and, if it ends up orphaned, the decimal itself. That last bit's not so important; if just the trailing zeroes can be removed, I'm certain I can kill off orphaned decimals. My various attempts are, at best, weak partial solutions. I can remove trailing zeroes and a few other tricks, but all fall short. The only guarantees about the incoming data are 1) the first field will always be a positive integer and no field will have more than 6 digits after the decimal.

So, how in the world can I remove from each field (except the first, to which this need not apply) any trailing zeroes after the decimal? For what it's worth, after digging through the forum, I've found no working solutions. A method (gsub? looping gsub? idunno...) that works would give as output for the above line:

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