You may be able to override a bit more of the code, though. Check out
Lib/json/encoder.py for the implementation, and have a look at the
floatstr() internal function; unfortunately you can't simply subclass
and override that, but perhaps overriding iterencode (which is where
floatstr is defined) would do the job.
