 I think there a two distinct problems
1. FreeCAD should only use doubles (in Properties)
2. Refine should take an precison argument.
(Most of the OCCT allows two specify the precision. If FreeCAD doesn't pass the right precision to OCCT, it's another bug.)

Make sense to go completely for double in all parameters!

I think we should go for doubles in the 0.14, which will cause a lot of testing.....

OCC uses Standard_Real etc. shouldn't we use that instead of double to avoid all rounding troubles now and in the distant future?

Can this be considered as fixed now?
