Math rounding rules normally state that anything of .5 and greater should be rounded up, not rounded down. So, for 99.5Hz, you really ought to be returning 100Hz, not 99Hz. However, you do have a point for 99.4Hz, which would be returned as 99Hz, and when set, it would result in something which isn't 99.4Hz. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
