round_lwcompound() static void round_lwcompound ( LWCOMPOUND *  comp, int  maxdd, bool  hasz, bool  hasm  ) static Set the precision of the coordinates of a compound curve to a number of decimal places. Note A CompoundCurve is a single continuous curve that may contain both circular arc segments and linear segments. That means that in addition to having well-formed components, the end point of every component (except the last) must be coincident with the start point of the following component. https://postgis.net/docs/using_postgis_dbmanagement.html#CompoundCurve
