Fixes #9722 and #9846. Floor and ceiling operations that take a specified scale do not take floating point operations as inputs, so Spark is implicitly casting the floating point inputs to decimal types before the operation. Casting of floating point to decimal types is a known, documented limitation, and it's disabled by default. Since these tests are not trying to test casting from floating point to decimal tests but rather just the floor and ceiling operations with a specified scale, the tests were updated to not test floating point inputs since those are known to not match Spark because of the implicit cast to decimal.
