## What changes were proposed in this pull request? See discussion on the JIRA (and dev). At heart, we find that math.log and math.pow can actually return slightly different results across platforms because of hardware optimizations. For the actual SQL log and pow functions, I propose that we should use StrictMath instead to ensure the answers are already the same. (This should have the benefit of helping tests pass on aarch64.) Further, the atanh function (which is not part of java.lang.Math) can be implemented in a slightly different and more accurate way. ## How was this patch tested? Existing tests (which will need to be changed). Some manual testing locally to understand the numeric issues. Closes #25279 from srowen/SPARK-28519.
