    Haven't  seen  the  original message, but it looks to me that
    the column is declared as decimal with  4  digits  after  the
    decimal  point. Therefore, all values get rounded at the time
    of INSERT/UPDATE. The above looks numerically right to me.

    Isn't  that  behaviour  correct?  Does  the  standard  define
    something else?
