You wouldn't want to get anywhere near this limit, though. The real practical limit is the number of significant figures in the floating-point format (about 16). The difference between 1e99 and the next smallest representable number is about 10^83 complete revolutions. For a 90:1 rotary and a 4096 count encoder you have an angular resolution of 3.5 arc seconds. or .0.001 degrees. After only 99999999999 degrees the double precision format can no longer discriminate between numbers one encoder count apart. A fairly fast rotary could get there in less than 100 years. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
