To me, in the context of describing feature dimensions, 2.1 is exactly the same as 2.10000000000000000... because 2.1 is a numerical value and unless noted on the drawing, the number of decimal places has no meaning. I think this notion that the number of decimal places is a standard is not correct, otherwise it would not need to be noted on the drawing. It really should be avoided, so the myth doesn't get perpetuated. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ 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 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
