Yes, in theory, but these tables have to be run using a higher number of bits than normal as they have a large effect in the reconstructed value. Check out the use of static tables with a second "continuation" table in "powf.c" from the Cephes single precision library "single.tgz". Compare it to the simplicity of "exp2f.c". http://www.netlib.org/cephes/ - Robin Green. ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ GDAlgorithms-list mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/gdalgorithms-list Archives: http://sourceforge.net/mailarchive/forum.php?forum_name=gdalgorithms-list
