You can certainly post QtRuby related questions here, but probably you'll get 
more answers using the qtruby mailing list kde-bindings / kde.org or the qtruby 
forum: http://rubyforge.org/forum/forum.php?forum_id=723.

Regarding your question, you can find an explaination of why this happens (and 
some workarounds) in this thread of the qtruby forum: 
http://rubyforge.org/forum/message.php?msg_id=67059

If you only want a quick solution, you can do the following: create a 
Qt::Locale object based on the C locale using Qt::Locale.c, sets its 
number_options property to Qt::Locale::OmitGroupSeparator and use its 
to_string method to create the string. Something like this:

x =  1234.567
l = Qt::Locale.c
l.number_options = Qt::Locale::OmitGroupSeparator
puts l.to_string(x)

Without changing the number_options property, you'll get a number separatorn 
the string (in the example, you'd get the string "1,234.567").

I hope this helps
