General Mach Discussion / Re: mach's rounding of measurements?

from what i understand.......... mach will go to the nearest step without going over 410.1= 410, 410.2= 410, 410.3=410, 410.4= 410
410.5=410, 410.6=410, 410.7=410, 410.8=410, 410.9=410, 410.912432=410.
so my understanding is correct mach rounds down to the nearest whole decimal?HuhHuh? without going over?
Basically, Yes, without going over. But see below.

my machine has an accuracy of .0024375....
i understand that it is not a cumulative problem as all measurements are from home!!!!!!!!!!!!!!!!!!!!!!!
the question is DOES MACH ROUND UP OR DOWN!
Mach doesn't think in terms of fractional steps, only integer steps. So there is no rounding. You want to move 1". Mach3 knows that 411 steps will go over, so it moves 410 steps. There's no such thing as 410.2 steps.
What you're calling "rounding down" is not really rounding. So perhaps this whole thread is just an issue with terminology.
