When rounding quantity margins (and perhaps also the actual amount of the quantity), we should never round to 0. 0 Margins indicate an exact value. That is a special case - showing "almost zero" as 0 (or hiding the mergin) would be misleading. E.g.: When rounding 2+/-0.016 to 1 digit after the decimal point (exp -1), we currently get 2+/-0, indicating an exact value. we should however get 2+/-0.02, ignoring the indicated rounding level and instead rounding to the most significant non-zero digit.
