The ext_attributes user interface is created with Dia's standard property 
system. The RealProperty - also used in non-custom objects - is indeed 
hardcoded to have two digits. See:
http://git.gnome.org/browse/dia/tree/lib/prop_geomtypes.c#n74

So the change you are requesting is requiring compilation.

The precision used for storing values in the diagram file is independent.
