The "format" here is simply the string format operation for Python as
referenced here:
http://docs.python.org/library/stdtypes.html#string-formatting
So for your case, instead of '%u', it should be '%f'. I have added
the above link to the Wiki page describing the Python module.
Have you tried running your plugin on the command line to see whether
your float was also converted to a large integer?
Cheers,
Bernard
