<p>The following is an example of the interpretation of the <b>mon_grouping</b> keyword. Assuming that the value to be formatted is
123456789 and the <b>mon_thousands_sep</b> is <tt>'&quot;</tt> , then the following table shows the result. The third column shows the
equivalent string in the ISO&nbsp;C standard that would be used by the <a href=
"../functions/localeconv.html"><i>localeconv</i>()</a> function to accommodate this grouping.</p>

<p>In these examples, the octal value of {CHAR_MAX} is 177.</p>

<p>IEEE&nbsp;Std 1003.1-2001/Cor&nbsp;1-2002, item XBD/TC1/D6/6 adds a correction that permits the Euro currency symbol and
addresses extensibility. The correction is stated using the term &quot;should&quot; intentionally, in order to make this a recommendation
rather than a restriction on implementations. This allows for flexibility in implementations on how they handle future currency
symbol additions.</p>

<p>IEEE&nbsp;Std 1003.1-2001/Cor&nbsp;1-2002, tem XBD/TC1/D6/5 is applied, adding the <b>int_[np]_*</b> values to the POSIX locale
definition of <i>LC_MONETARY .</i></p>

<h5><a name="tag_01_07_03_04"></a>LC_NUMERIC</h5>

<p>See the rationale for <i>LC_MONETARY</i> for a description of the behavior of grouping.</p>

<h5><a name="tag_01_07_03_05"></a>LC_TIME</h5>

<p>Although certain of the conversion specifications in the POSIX locale (such as the name of the month) are shown with initial
capital letters, this need not be the case in other locales. Programs using these conversion specifications may need to adjust the
capitalization if the output is going to be used at the beginning of a sentence.</p>

<p>The <i>LC_TIME</i> descriptions of <b>abday</b>, <b>day</b>, <b>mon</b>, and <b>abmon</b> imply a Gregorian style calendar
(7-day weeks, 12-month years, leap years, and so on). Formatting time strings for other types of calendars is outside the scope of
IEEE&nbsp;Std&nbsp;1003.1-2001.</p>

<p>While the ISO&nbsp;8601:2000 standard numbers the weekdays starting with Monday, historical practice is to use the Sunday as the
