Thanks to Dave, Jake and Geoffrey even if my answer was OT... thanks
also for the perl links
For Jake:
the problem is that in your example I think that perl assumes they are
numbers and renders them correspondingly. In my case, I get them as
strings during the workflow, so that perl doesn't manage
automatically...
For example:
perl -le '$foo=1.00; print $foo'
1
[gcecchi at tekkaman ~]$ perl -le '$foo="1.00"; print $foo'
1.00
BTW, it was the correct regex that I missed. Simple to read after you
pointed out, but (at least for me) difficult to catch initially... ;-)
Actually I had to make the job in awk where I then easily got the same
effect with:
sub(/\.?0+$/, "", foo)
Thanks again and hope to repay in some way ...
