Hello list. I have a model "PP" with a "float" field "val" and a
modelform for this model

For update the data of a existent "PP" I use a form like this

Form_for_PP(request,POST, instance=instance)

Now my question is, Can I change the initial data  for the field
"val"?

I want to do this:

If the value in "val" is 12345.6, the resulting form must to have the
value "12.345,6" (the same value, but formatted)

I can't find the way to do this when I use an instance. Set an
"initial" don't  work, the returning value is always the existing in
the DB.

Somebody can help me?

Thanks for read, and sorry for my poor english.
