Does openFHE encapsulate the implementation of homomorphic division?

Hi @hamm ,

Not sure what you mean by `encapsulation`. There is currently an implementation of division using Chebyshev interpolation (written as 1/x, where x is between 1 and large `bound`; x cannot be zero) for the supplied range and polynomial degree. The implementation will be similar to evaluation of other functions using Chebyshev interpolation; see [openfhe-development/function-evaluation.cpp at main · openfheorg/openfhe-development · GitHub](https://github.com/openfheorg/openfhe-development/blob/main/src/pke/examples/function-evaluation.cpp) for more details.
