Interesting behaviour with units

Is there a known explanation for the next? I would think that the resulting units should be the same, but apparently not.

This was with Prime 7.

I agree that its a very inconsistent behaviour.
As Prime is not using SUC (static unit check) is should always apply a unit to zero values.

Example done in Prime 9

 

You may consider reporting it to PTC support.

 

BTW multiple vectorizations as seen in your screenshot have no special effect. One large vectorization arrow over the whole expression is all thats needed.

Thanks!  I suppose I will. Especially as it seems to persist in newer versions. It seems to work as long as at least one of the boolean rows returns true.

 

About the vectorization: Was it always so? I seem to recall that at some time I needed it to get the result, but it is too long ago to dig up.

As far as I am aware multiple vectorizations never had any effect in Mathcad, but then my memory can also be wrong ...
