EveyWu commented on CALCITE-6259:
----------------------------------
log10 is defined in the SqlStdOperatorTable, In my opinion, there is no
guarantee that the execution results of different engines will be consistent.
Calcite defines its criteria for execution results, which can be similar to
common engine results, but exact consistency is not guaranteed.
> Return the result with the log10 and log functions of argument 0
