Hi Y'all,

Does anyone have any advice on how to safely persist arrangements? My arrangement is based on an exact number type and the combination of a rather ugly pile of curves...it is very possible that some of the intersections required to form the topologically correct map cannot be represented with raw 64-bit floats.

How can I write an arrangement out to disk such that I can both read it back without redoing the intersection calculations and be sure that it is topologically correct?

thanks
Ben
