[postgis-users] PostGIS new geometry type with defined precision?

[Giunta Igor]

How can a precision be assigned to a geometry, e.g. a point/line/polygon to 3 decimals, in order that any input/output will be given in that precision (without usage of rounding functions like snap2grid)
How can the problem be tackeld? Shall we request to include new types? Or shall we rather let develop a new feature?

I guess we are not the first users facing this problem.
