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 <strong><code>CHAR_MAX</code></strong>,
|
|
no further grouping is done. If an array element is equal to 0, the previous
|
|
element should be used.
