Hi @trandus,

I want to add more detail to what @iquah wrote. We have an example of large-precision comparison (sign function) at [openfhe-development/eval-sign.cpp at v1.0.1 · openfheorg/openfhe-development · GitHub](https://github.com/openfheorg/openfhe-development/blob/v1.0.1/src/binfhe/examples/eval-sign.cpp) Under the hood, it uses the algorithm proposed in [Large-Precision Homomorphic Sign Evaluation using FHEW/TFHE Bootstrapping](https://eprint.iacr.org/2021/1337).

Also I suggest reading a related topic: [Optimization of Homomorphic Comparison Algorithm on RNS-CKKS Scheme](https://openfhe.discourse.group/t/optimization-of-homomorphic-comparison-algorithm-on-rns-ckks-scheme/256)
