    27           <para>Fixnums on 32-bit systems use 30 bits and are in the
    28             range XXX through YYY.  Fixnums on 64-bit systems use 61-bits
    29             and are in the range XXX through YYY. (see <xref

     28          range -536870912 through 536870911.  Fixnums on 64-bit
     29          systems are 61 bits long, and are in the range
