Multiply with Numeric Types

@data = 
    SELECT * FROM 
        ( VALUES
        ((int)38)
        ) AS T(aNumber);

DECLARE @val int = 5;

@result =
    SELECT 38 * 5 AS Int1,
           aNumber * 5 AS Int2,
           aNumber * @val AS Int3,
           aNumber * (int?)null AS intNull,
           (aNumber * (double)12345).GetType().Name AS intAndDouble,
           (aNumber * (long)12345).GetType().Name AS intAndLong
    FROM @data;
