The <em>p_sign_posn</em>, and <em>n_sign_posn</em> contain a string
of formatting options. Each number representing one of the above listed conditions.
</p>
<p class="para">
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.
