Hello, is there a way to evaluate x % 1 on a encrypted value ? If so, in which scheme? Thank you
x % 1 (I assume x is a real number) can be evaluated using lookup tables in FHEW/TFHE (with prior scaling up to integers) or in CKKS (using a polynomial approximation, e.g., of a sine wave). The latter approach is used internally in CKKS bootstrapping.
