So, as long as I specify coordinates in 0.001" increments (which is
what I normally do), there's an exact representation in motor
coordinates (and no quantization error).
You are rounding which is fine if you are cutting out a square say but
what about a circle or a diagonal or a spline? You are effectively
adding the quantization error before you move the motors.
Unless you have a noiseless analogue computer or you stick with square
components there will always be some quantization error even before
the motors :)
Not that this matters.
