Overview
In https://github.com/delta-io/delta/pull/5186, we are kind of customizing the type check and value comparison among numerics.
Technically we could streamline the implementation via a refactor to 1.figure out the narrowest type 2.transform the expression via implicit cast expression 3.simplify the value comparision.
Doing so today will have 1 test failure fails due to float -> double convertion 84.08 -> 84.08000183105469 We need to investigate this logic in implicit cast and then do refactoring to unify the expression logic
