* $Log$
* Revision 1.4 2006/05/04 14:05:31 strk
* * source/headers/geos/util/math.h: provided an util::round() method being an inline proxy to call appropriate default rounding function for the whole GEOS codebase. Currently pointing at util::java_math_round() being the last being used.
*
* Revision 1.3 2006/04/07 12:37:53 mloskot
* Added java_math_round() function for Asymmetric Arithmetic Rounding. Small fixes in Unit Tests.
*
* Revision 1.2 2006/04/06 21:30:36 strk
* Added missing rint_vc() forward declaration
*
* Revision 1.1 2006/03/09 16:46:49 strk
* geos::geom namespace definition, first pass at headers split
*
