[postgis-devel] SnapToGrid support of circular string

Does it make sense to threat a CircularString the
same as a LineString when it comes to snapping it
to a grid ?

Adding such support would help fixing ticket #183,
which is a regress test failing due to precision on 32bits:

   CIRCULARSTRING(0 0,0.500000000000184 1.20710678118655,1 0),
   (1 0,0 1)

Sorry for the lame question but I haven't found semantic
of CIRCULARSTRING on the postgis manual
