Computational resolution:
1,000 increments/mm
Programmed path:
97.3786mm
Effective value =
97.379mm
To keep the executed rounding more traceable, it is reasonable to use powers
to the 10th for the computational resolution (100, 1000, 10.000).
In MD 9004: DISPLAY_RESOLUTION, you can set the number of decimal
places after the decimal point for the position values on the operator panel.
The limitation of the input limits depends on the display and input possibilities on
the operator panel.
This limit is reached at 10 digit positions plus decimal point plus sign.

Check MD 10200: INT_INCR_PER_MM = 10,000 [incr. /mm]:
Example of related parts program:
N20 G0 X 1.0000 Y 1.0000 ;
Axes move to position
X=1.0000mm, Y=1.0000mm;
N25 G0 X 5.0002 Y 2.0003 ;
Axes move to position
X=5.0002mm, Y=2.0003mm
