      Description

      SELECT
      		 
        ROUND(18446744073709551615,rand()*0) AS c1,
      		 
        ROUND(18446744073709551615.0,rand()*0) AS c2;


      +----------------------+------------------------+
      		 
      | c1                   | c2                     |
      		 
      +----------------------+------------------------+
      		 
      | 18446744073709552000 | 18446744073709551615.0 |
      		 
      +----------------------+------------------------+

      The result for c1 is wrong. It should be equal to 18446744073709551615, like c2, just without the '.0' part.
