round_lwcurvepoly() static void round_lwcurvepoly ( LWCURVEPOLY *  cpoly, int  maxdd, bool  hasz, bool  hasm  ) static Set the precision of the coordinates of a curve polygon to a number of decimal places. Note A CurvePolygon is like a polygon, with an outer ring and zero or more inner rings. The difference is that a ring can be a CircularString or CompoundCurve as well as a LineString. https://postgis.net/docs/using_postgis_dbmanagement.html#CurvePolygon
