[I] Math functions differ from Spark in the last digits [datafusion-comet]

["andygrove (via GitHub)" <gi...@apache.org>]

andygrove opened a new issue, #6797:
URL: https://github.com/apache/datafusion-comet/issues/6797

   Found while enabling `spark.comet.exec.localTableScan.enabled` by default in draft PR #6780 (Spark 4.1 SQL tests and `[scans]` job). Part of #4347.
   
   MathFunctionsSuite asinh, cosh, tan, cot, atanh, cbrt, exp, pow/power, atan2 fail on exact comparison once inputs come from LocalTableScan. Check which differ from JVM libm and whether to mark Incompatible or compute differently.
