Content
The csv.writer needs a special case for floats to print them to full precision. See http://stackoverflow.com/a/8455313/1001643 In Py2.7, the csv.writer converts floats to strings using str(). This will store 1323494016.8556759 as '1323494016.86' and unnecessarily throw away precision. In Py3.2, this isn't a problem because float.__str__ now returns full precision, the same a float.__repr__.
