### Describe the enhancement requested Follow-up of https://github.com/apache/arrow/pull/36289#discussion_r1267909098. I am in favor of removing integer compatibility for `trunc`, `floor` and `ceil` for the following reasons: 1. Mathematically they are no-ops for integers, so it doesn't make much sense to support them as a function. 2. The current implementation casts ints to floats, which may yield unexpected results due to float precision issues. 3. It's very simple to remove it, by just deleting several lines of code, as @jorisvandenbossche mentioned [here](https://github.com/apache/arrow/pull/36289#discussion_r1267931632), along with some small changes in tests and docs. 4. The support for integers was probably unintentional, just like the case for `round`. The downside is, all the SQL engines, along with Numpy and R, support floor(int), and the result type is double, which means our current implementation is consistent with them. cc @pitrou @jorisvandenbossche @westonpace ### Component(s) C++ -- This is an automated message from the Apache Git Service.
