Set the geometry's precision, optionally rounding all its coordinates to the precision grid (if it changes).

Note that operations will always be performed in the precision of the geometry with higher precision (smaller "gridSize"). That same precision will be attached to the operation outputs.

Parameters

gridSize	size of the precision grid, or 0 for FLOATING precision.
flags	The bitwise OR of one of more of the precision options NULL on exception or a new GEOSGeometry object
