[NTG-context] mkiv digits/units zero padding not working

Hi, I’m trying to get \digits{15.0=}±\digits{1.00} \digits{_8.12}±\digits{0.34} horizontally aligned as 15.0 ±1.00 8.12±0.34 But I get 15.0±1.00 8.12±0.34 instead. From the source (phys-dim.mkiv), I can see that “=“ should expand to \hphantom{0}. (I think \zeropoint in the table is outdated, since \def\zeropoint\hphantom{0} does not solve the problem either.) I can’t use tabulate or alignment in math mode for this problem unfortunately. Any hints would be very welcome. Thanks Benjamin
