Maybe I'm not understanding your meaning, but consider that we calculate many different things with different precision requirements. Speed and altitude, for example, are probably fine rounded to the nearest whole number. Lat and long, however, really do need to have about 6 decimal places of accuracy. So I'm not sure how you'd go about choosing the fixed point you're going to use. > > > > _______________________________________________ > Flightgear-devel mailing list > [EMAIL PROTECTED] > http://mail.flightgear.org/mailman/listinfo/flightgear-devel -- Tony Peden <[EMAIL PROTECTED]> _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
