Detailed Description

   template<typename _CharT, typename _InIter>class std::num_get< _CharT, _InIter >
       Primary class template num_get.

       This facet encapsulates the code to parse and return a number from a string. It is used by
       the istream numeric extraction operators.

       The num_get template uses protected virtual functions to provide the actual results. The
       public accessors forward the call to the virtual functions. These virtual functions are
       hooks for developers to implement the behavior they require from the num_get facet.

       [inline]
       Numeric parsing. Parses the input stream into the bool v. It does so by calling
       num_get::do_get().

       If ios_base::boolalpha is set, attempts to read ctype<CharT>::truename() or
       ctype<CharT>::falsename(). Sets v to true or false if successful. Sets err to
       ios_base::failbit if reading the string fails. Sets err to ios_base::eofbit if the stream
       is emptied.

       If ios_base::boolalpha is not set, proceeds as with reading a long, except if the value is
       1, sets v to true, if the value is 0, sets v to false, and otherwise set err to

       (iter_type__in, iter_type__end, ios_base &__io, ios_base::iostate &__err, long &__v) const
       [inline]
       Numeric parsing. Parses the input stream into the integral variable v. It does so by
       calling num_get::do_get().

       Parsing is affected by the flag settings in io.

       The basic parse is affected by the value of io.flags() & ios_base::basefield. If equal to
       ios_base::oct, parses like the scanf o specifier. Else if equal to ios_base::hex, parses
       like X specifier. Else if basefield equal to 0, parses like the i specifier. Otherwise,
       parses like d for signed and u for unsigned types. The matching type length modifier is
       also used.

       Digit grouping is interpreted according to numpunct::grouping() and
       numpunct::thousands_sep(). If the pattern of digit groups isn't consistent, sets err to
       ios_base::failbit.

       If parsing the string yields a valid value for v, v is set. Otherwise, sets err to
       ios_base::failbit and leaves v unaltered. Sets err to ios_base::eofbit if the stream is
       emptied.

       Parameters:
           in Start of input stream.

   template<typename _CharT , typename _InIter > iter_type std::num_get< _CharT, _InIter >::get
       (iter_type__in, iter_type__end, ios_base &__io, ios_base::iostate &__err, unsigned int
       &__v) const [inline]
       Numeric parsing. Parses the input stream into the integral variable v. It does so by
       calling num_get::do_get().

       Parsing is affected by the flag settings in io.

       The basic parse is affected by the value of io.flags() & ios_base::basefield. If equal to
       ios_base::oct, parses like the scanf o specifier. Else if equal to ios_base::hex, parses
       like X specifier. Else if basefield equal to 0, parses like the i specifier. Otherwise,
       parses like d for signed and u for unsigned types. The matching type length modifier is
       also used.

       Digit grouping is interpreted according to numpunct::grouping() and
       numpunct::thousands_sep(). If the pattern of digit groups isn't consistent, sets err to
       ios_base::failbit.

       If parsing the string yields a valid value for v, v is set. Otherwise, sets err to
       ios_base::failbit and leaves v unaltered. Sets err to ios_base::eofbit if the stream is
       emptied.

       Parameters:
           in Start of input stream.
           end End of input stream.
           io Source of locale and flags.
           err Error flags to set.
           v Value to format and insert.

       Returns:
           Iterator after reading.

       const [inline]
       Numeric parsing. Parses the input stream into the pointer variable v. It does so by

       The input characters are parsed like the scanf p specifier.

       Digit grouping is interpreted according to numpunct::grouping() and

       Note that the digit grouping effect for pointers is a bit ambiguous in the standard and
       shouldn't be relied on. See DR 344.

       If parsing the string yields a valid value for v, v is set. Otherwise, sets err to
