[/COLOR]My sed and datpal's awk solution fail in this case

Code:
$ echo 1200.00200300 | sed "s/\.0\{1,\}//g"
1200200300
$ echo 1200.00200300 | awk '{ if ($0 ~ /\./){ sub("0*$","",$0); sub ("\.$","",$0);} print}'
1200.00200

Code:
$ echo 1200.00200300 | awk -F"," -v OFS="," ' { for(i=0;NF- i++;){sub("[.]*0+ *$","",$i)};$1=$1 }1 '
1200.002003


It works fine for me anbu23
Code:
 echo 1200.00200300 | awk '{ if ($0 ~ /\./){ sub("0*$","",$0); sub ("\.$","",$0);} print}'
1200.002003

In fact what u gave will break for whole numbers
Code:
 echo 100 | awk -F"," -v OFS="," ' { for(i=0;NF- i++;){sub("[.]*0+ *$","",$i)};$1=$1 }1 '
1

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
