I'm not a mathematician, but my gut feeling says that comparing floating point values (google for it) is not just about the equal sign. Google for "comparing floating point values" and you'll find plenty of information. I'm not sure if this is something the user should compensate for, or if RRDtool needs to be altered. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
