    Description

      When we use the division function to calculate, we find that if there is a negative number type string, the result will be inconsistent with the expectation

      select 0/-4; – actual: 0.0000, expect: 0
      select '0'/-4; – actual: -0, expect: 0

      MySQL has verified this as a bug. please see https://bugs.mysql.com/bug.php?id=109837. so I consider it also a bug for mariadb.
