the standard mandates that all dimensions (note particularly those calculated with 1.4142... sqrt 2)) be rounded to the millimeter. in the smaller sizes this error becomes significant and affects both linear dimensions and aspect ratios
the standard also has mfring tolerances allowing errors on the order of millimeters
