Does that work on your system? I suppose I might have a different version of awk. It appears to chop off everything up to the decimal place, at least on my system:

Code:
# echo 1200,135.000000,12.30100,3212.3200,1.759403,1230,101.101010,100.000000 | awk 'BEGIN{FS=OFS=","}{for(i=1;++i<=NF;)$i=int($i)}1'
1200,135,12,3212,1,1230,101,100

It appears that anbu23's solution works well. It makes sense, even, except that I don't understand a couple of minor things. Here's where my dampness behind the ears shows through, I'm afraid...

Code:
awk -F"," -v OFS="," ' { for(i=0;NF-i++;){ if($i ~ /[.]/){ sub("[.]*0+ *$","",$i) }}$1=$1}1'

I don't understand the purpose of the $1=$1 and the 1. They appear critical, but what do they do? Many thanks for the solutions offered. They serve well to show me where I can focus my learning.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
