How can you use division? of two encrypted inputs?

kimlaine commented 3 weeks ago

This functionality is not supported. One issue is that plaintext elements form an algebraic ring but not a field, so division may be impossible. Basically, computing inverses is not a very natural operation in the plaintext space. Several research groups have proposed different approaches for approximating inverses, but these are very costly to run and may not be viable solutions for your application.
