Incongruence in matrix units

[francesco_17]

Good morning

Can anybody explain me this (see screenshot)?
After the "=" in the matrix I see what are the right units (which are no units for the last 2 elements).

But when I try to use them later, it looks as if the last 2 elements are in m.

I attached also the mathcad file. I use Mathcad prime 3.1

Thanks

That's because Mathcad (and apparently Prime too), will append units to a value of 0 whenever it is convenient (to the discretion of internal algorithms).

You can check equality between 2 m and 0 m, as well as between 2 m and 0, and they both result in False (not True). but an equality check between 2m and 3 throws an error.

I guess something similar is going on here.

Success!

Thats where zero and Zero come to play:

Its explained in more detail in the Prime Migration Guide (see attached)
