It doesn't, so it's a bug. But it's extremely unlikely that it will ever
have any impact on the user. You will e.g. need a double decker bridge that
was surveyed with high precision DGPS equipment and then you can't use
Potlatch. The variables I'm using have 10cm resolution.

So it's a bug that has become a feature.
