    Description

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a DECIMAL(30,1)) ENGINE=ColumnStore;
      INSERT INTO t1 VALUES (-9223372036854775807.9);
      SELECT a, ROUND(a), CAST(ROUND(a) AS SIGNED) FROM t1;
      

      +------------------------+----------------------+--------------------------+
      | a                      | ROUND(a)             | CAST(ROUND(a) AS SIGNED) |
      +------------------------+----------------------+--------------------------+
      | -9223372036854775807.9 | -9223372036854775808 |                     NULL |
      +------------------------+----------------------+--------------------------+
      

      NULL in the last column looks wrong.
