I doubt this has anything to do with limits. Please try harder to
produce *minimal
reproducible* problem reports.
As for factoring, it doesn't make sense to factor approximate numbers like
8.14, which cannot be represented exactly in binary floating-point. But if
you insist, the factorization is:
factor(rationalize(8.14)) =>
5*6113*18740440949/2^46
-s
