Calculate the current ATK X/0; switch ATK/DEF and freeze the values — now you have a 0/X powerhouse

Calculator has a continuous effect, so I was wondering if after switching, its 0 attack and defense now become X/X, with the DEF X at a set value when Inverse Universe was applied.

well, you can found the answer by looking at Inverse Universe card ruling itself

Quote:

After "Inverse Universe" resolves, monsters whose ATK and DEF are calculated or modified because of their own individual effects have their ATK and DEF "frozen" at the switched values.
Examples:
The ATK and DEF of "Tragoedia" will not change even if the number of cards in your hand changes.
