<p><b>Discussion:</b></p>
<p>
In 22.2.2.1.1, we have a list of overloads for num_get&lt;&gt;::get().
There are eight overloads, all of which are identical except for the
last parameter.  The overloads are: 
</p>
<ul>
<li> long&amp; </li>
<li> unsigned short&amp; </li>
<li> unsigned int&amp; </li>
<li> unsigned long&amp; </li>
<li> short&amp; </li>
<li> double&amp; </li>
<li> long double&amp; </li>
<li> void*&amp; </li>
</ul>

<p>
There is a similar list, in 22.2.2.1.2, of overloads for
num_get&lt;&gt;::do_get().  In this list, the last parameter has
the types: 
</p>
<ul>
<li> long&amp; </li>
<li> unsigned short&amp; </li>
<li> unsigned int&amp; </li>
<li> unsigned long&amp; </li>
<li> float&amp; </li>
<li> double&amp; </li>
<li> long double&amp; </li>
<li> void*&amp; </li>
</ul>

<p>
These two lists are not identical.  They should be, since
<code>get</code> is supposed to call <code>do_get</code> with exactly
the arguments it was given.
</p>


<p id="res-275"><b>Proposed resolution:</b></p>
<p>In 28.3.4.3.2.2 <a href="https://wg21.link/facet.num.get.members">[facet.num.get.members]</a>, change</p>
<pre>
  iter_type get(iter_type in, iter_type end, ios_base&amp; str,
                ios_base::iostate&amp; err, short&amp; val) const;
</pre>
<p>to</p>
<pre>
  iter_type get(iter_type in, iter_type end, ios_base&amp; str,
                ios_base::iostate&amp; err, float&amp; val) const;
</pre>
