Sure, CoordinateSystem know about axis, but axis doesn't know about=20
precision model (at least not in CTS 1.0 specification). It make sense;=20
axis tell for example that the first ordinate has values increasing=20
North; it doesn't said what the precision should be for those values. We=20
can very well render two geometries on the same map, with one geometry=20
using float[] data and the second geometry using double[] data.

Softwares like Excel or Calc have a "precision" attribute under the=20
"Axis" tab. But this is the precision to apply on the numbers to be=20
formatted as labels. This is a formatting issue which has nothing to do=20
about the precision of the underlying data. All data to be rendered on=20
the same graph (or using the same CoordinateSystem) uses the same axis,=20
no matter if their data are actually integers or floats.
