You can try redefining the Float#to_s method after creating the application, 
using the code I suggested inside it. This works in a simple example, but I'm 
not sure what would happen in a real situation.

require 'Qt4'

a = Qt::Application.new []

class Float
  def to_s
    l = Qt::Locale.c
    l.number_options = Qt::Locale::OmitGroupSeparator
    l.to_string(self)
  end
end
x =  1234.567
puts x
