<a name="class-descrip"><h3>Class Description</h3></a>
<p>
The numpunct class describes a class used to specify the numeric punctuation by
providing the classic "C" numeric formats.<br>
<br>
The syntax for the number formats are as follows:<br>
<br>
Integer values have this format:
</p>
<pre>
integer : : = [sign} units
sign : : = plusminus [whitespace]
units : : = digits [thousands-sep units]
digits : : = digit [digits]
</pre>
<p>
<em>digit</em> represents the radix set specified by <em>fmtflags</em> argument value.
<em>whitespace</em> is determined by the facet ctype<charT>. <em>thousands-sep</em>
amd <em>decimal-point</em> are the results of the corresponding numpunct<charT> members.<br>
<br>
The floating-point values have:
</p>
<pre>
floatval : : = [sign] units [decimal-point [digits]] [e [sign] digits] |
[sign] decimal-point digits [e [sign] digits]
e : : = 'e' | 'E'
</pre>
<p>
The number of digits between <em>thousands-seps</em> is as specified by <em>do_grouping()</em>.
For parsing, if the <em>digits</em> portion contains no thousands-separators then no grouping constraint is used.
</p>
<hr>
<a name="id"><h3>locale::id</h3></a>
<p>
<em>locale::id</em> is a class used to provide an identification of a locale facet interfaces used as
an index for lookup and to encapsulate initialization.

Method grouping()</a>
Access Public
Classification Accessor
Syntax string grouping() const;
Parameters None
Returns This method returns a vector in which each element
is an integer value used to represent the number

<pre>
<a name="numpunct">
Method numpunct()</a>
Access Public
Classification Constructor
Syntax explicit numpunct(size_t refs = 0);
Parameters <em>refs</em>, if the refs argument = 0 then the destruction
of the object is delegated to the locale or locales
which contain it. If refs = 1 then the object must
be explicitly deleted. The locale will not delete
it. The object can then be maintained across
the lifetime of multiple locales.
Returns None
</pre>
<h3>Description</h3>
<p>
The constructor constructs a numpunct facet object.
</p>

Classification Destructor
Syntax ~numpunct();
Parameters None
Returns None
</pre>
<h3>Description</h3>
<p>
The destructor destroys a numpunct facet object.
