      Description

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a DECIMAL(10,1)) ENGINE=ColumnStore;
      INSERT INTO t1 VALUES (-1.6);
      SELECT CEIL(a), LEFT('abc', CEIL(a)) FROM t1;
      

      +---------+----------------------+
      | CEIL(a) | LEFT('abc', CEIL(a)) |
      +---------+----------------------+
      |      -1 | abc                  |
      +---------+----------------------+
      

      Looks wrong. The expected result is:

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a DECIMAL(10,1)) ENGINE=InnoDB;
      INSERT INTO t1 VALUES (-1.6);
      SELECT CEIL(a), LEFT('abc', CEIL(a)) FROM t1;
      

      +---------+----------------------+
      | CEIL(a) | LEFT('abc', CEIL(a)) |
      +---------+----------------------+
      |      -1 |                      |
      +---------+----------------------+
