## Post #1 by @Leonardo_Moretti

Archetype editor uses the attribute is\_integral for DV\_PROPORTION, but there is not an equivalent RM attribute\.
Should it be considered as a contraint on precision RM attribute \(when is\_integral=true \-\->  precision=0\)?
Anf when is\_integral is false, this means precision should be>= 1? or whatever?
Why is not a precision attribute used?

Thank you\.
Regards
