the problem is caused by locale settings; you are probably using LANG=de_DE.

Please try to set "LC_ALL=C; export LC_ALL" at the beginning of the script.

With de_DE locale, awk should use "," as decimal dot, both in the input and
the output.  Unfortunately, this feature has some bugs.  Arnold Robbins,
the gawk maintainer, knows about the bugs, so they'll probably be fixed
when 3.1.4 is out.  For now, it's better so stick to C locale.

Hope I gave you all info you need.

Happy awking,
