00049  * Revision 1.4  2006/05/04 14:05:31  strk
00050  * * 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.
00051  *
00052  * Revision 1.3  2006/04/07 12:37:53  mloskot
00053  * Added java_math_round() function for Asymmetric Arithmetic Rounding. Small fixes in Unit Tests.
00054  *
00055  * Revision 1.2  2006/04/06 21:30:36  strk
00056  * Added missing rint_vc() forward declaration
00057  *
00058  * Revision 1.1  2006/03/09 16:46:49  strk
00059  * geos::geom namespace definition, first pass at headers split
