       *  @brief  Numeric parsing.

       *

       *  Parses the input stream into the bool @a v.  It does so by calling

       *  num_get::do_get().

       *

       *  If ios_base::boolalpha is set, attempts to read

       *  ctype::truename() or ctype::falsename().  Sets

       *  @a 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 @a v to true, if the value is 0, sets

       *  @a v to false, and otherwise set err to ios_base::failbit.

       *

       *  @param  in  Start of input stream.

       *  @param  end  End of input stream.

       *  @param  io  Source of locale and flags.

       *  @param  err  Error flags to set.

       *  @param  v  Value to format and insert.

       *  @return  Iterator after reading.
