I'm only quessing as I don't use ArcMap, but I'm thinking that ArcMap 
does not understand data type "double precision" and probably maps it to 
"numeric" but without any decimal points.

You could try creating a view or redefining the columns as numeric(14,7) 
or whatever is appropriate and see if that works better.
