Fra http://dev.mysql.com/doc/refman/4.1/en/numeric-type-overview.html:

[...]

  M indicates the maximum display width. The maximum legal display
  width is 255. Display width is unrelated to the storage size or
  range of values a type can contain, as described in Section 11.2,
  Numeric Types.

[...]

  * INT[(M)] [UNSIGNED] [ZEROFILL]

    A normal-size integer. The signed range is -2147483648 to
    2147483647. The unsigned range is 0 to 4294967295.

Det er altså ren fremvisning
