>&#13;     The grouping fields contain arrays that define the way numbers should be
     grouped. For example, the monetary grouping field for the nl_NL locale (in
     UTF-8 mode with the euro sign), would contain a 2 item array with the
     values 3 and 3. The higher the index in the array, the farther left the
     grouping is. If an array element is equal to <TT
CLASS="constant"
><B
>CHAR_MAX</B
></TT

     no further grouping is done. If an array element is equal to 0, the previous
     element should be used.
