[jira] [Created] (FLINK-10008) Improve the LOG function in Table to support bases less than 1

Xingcan Cui created FLINK-10008:
-----------------------------------

             Summary: Improve the LOG function in Table to support bases less than 1
                 Key: FLINK-10008
                 URL: https://issues.apache.org/jira/browse/FLINK-10008
             Project: Flink
          Issue Type: Improvement
          Components: Table API &amp; SQL
            Reporter: Xingcan Cui


Currently, the {{LOG}} function in SQL/Table API restricts the base to be greater than 1. We should extend it to support bases less than 1 (e.g., {{LOG(0.01, 0.1)}} should return 2.0).
