Discussion:

In 22.2.2.1.1, we have a list of overloads for num_get<>::get(). There are eight overloads, all of which are identical except for the last parameter. The overloads are:

• long&
• unsigned short&
• unsigned int&
• unsigned long&
• short&
• double&
• long double&
• void*&

There is a similar list, in 22.2.2.1.2, of overloads for num_get<>::do_get(). In this list, the last parameter has the types:

• long&
• unsigned short&
• unsigned int&
• unsigned long&
• float&
• double&
• long double&
• void*&

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

Proposed resolution:

In 28.3.4.3.2.2 [facet.num.get.members], change

  iter_type get(iter_type in, iter_type end, ios_base& str,
                ios_base::iostate& err, short& val) const;

to

  iter_type get(iter_type in, iter_type end, ios_base& str,
                ios_base::iostate& err, float& val) const;
