New submission from Sebastian Billaudelle <stein at cream-project.org>:

Hi there,

I just recognized a weird behaviour of the json module...

Dumpig a float like 0.1 I get some crazy output.

Here is an example:

>>> import json
>>> json.dumps([.1])
'[0.10000000000000001]'

Very simple to reproduce;)

- Sebastian
