Re: [jts-dev] PrecisionModel.makePrecise

You can do this:

coord.setZ( pm.makePrecise ( coord.getZ() ) );

I note in PrecisionModel the method:

/**
* Rounds a Coordinate to the PrecisionModel grid.
*/
public void makePrecise(Coordinate coord)
{
// optimization for full precision
if (modelType == FLOATING) return;

coord.x = makePrecise(coord.x);
coord.y = makePrecise(coord.y);
//MD says it's OK that we're not makePrecise'ing the z [Jon Aquino]
}

I would like to be able to apply a precision factor eg round to 1mm (0.001/3) any Z values.

Given what this method does, what is the best way/place to round/makePrecision any Z ordinates?
