Discussion:

At the end of 28.3.4.3.3.3 [facet.num.put.virtuals] (in p6), the return value is said to be obtained by calling truename or falsename on the wrong facet: ctype should be replaced by numpunct.

Proposed resolution:

This wording is relative to N3691.

1. Edit 28.3.4.3.3.3 [facet.num.put.virtuals] p6 as indicated:

   -6- Returns: If (str.flags() & ios_base::boolalpha) == 0 returns do_put(out, str, fill, (int)val), otherwise obtains a string s as if by

   string_type s =
     val ? use_facet<ctypenumpunct<charT> >(loc).truename()
         : use_facet<ctypenumpunct<charT> >(loc).falsename();
   

   and then inserts each character c of s into out via *out++ = c and returns out.
