patch 9.1.1684: min()/max() does not handle float data types

Problem:  min()/max() does not handle float data types
          (ubaldot)
Solution: Extend min() and max() to every comparable type
          (LemonBoy)

Re-use the logic used for plain old comparison operators, this way we
gain support for float values and unify the logic handling the
comparisons.

fixes: #18052
closes: 18055
