Units48 v1.0: units the 48 way

[tcab]

How do I move numbers from the Units48 app - to and from the normal Prime home view?

If I'm using my Prime, in the middle of some calculations, and need to do some conversions on my interim results - how do I get those numbers into the app and back out when I'm done?

In the App, I cannot even use Sto to store numbers into variables, and certainly referring to variables doesn't work either given the Alpha key has been taken over as a simulated [Left Shift] key.
