Hm, It seems to work if you use locale: 
perl -we 'use POSIX; use locale; setlocale LC_NUMERIC, "fr_FR"; $x = "
+123,45"; $x+=0.1; print $x; setlocale LC_NUMERIC, ""; $x += 0.1; prin
+t $x;'

Update: this does not work: 
perl -we 'use POSIX; use locale; setlocale LC_NUMERIC, "fr_FR"; $x = "
+123,45";  print $x; setlocale LC_NUMERIC, ""; $x += 0.1; print $x;'

So what I do now is to add 0 if it looks_like_number() and everything works fine. At least what I've tested until now...

    ah! In that case, 

    (my $tmp = $s) =~ s/,/./;
$s = $tmp if looks_like_numbers($tmp);

    You'd be better of specifying which columns are numeric, though. Text::CSV_XS can even take advantage of that information if you tell it (via types).
