Put numerical value

The function writes the characters resulting from the formatting operation into the sequence whose first character is pointed by out.

An iterator to the character right after the last element written to the output sequence is returned by the function.

Internally, this function simply calls the virtual protected member do_put, which by default produces a sequence with the same format as printf does for the format specified that corresponds to the type of argument val taking into account str's format flags and field width. The function uses the locale selected in str to obtain format details (through facet numpunct) and to widen characters (with ctype::widen) when necessary.

out

Iterator pointing to the first character where the representation as a sequence of characters is stored.
The sequence shall be long enough to contain the whole expression.
Member type iter_type is the facet's iterator type (defined as an alias of num_put's second template parameter, OutputIterator). By default, this is an ostreambuf_iterator, allowing implicit conversions from basic_ostream objects.

str

Object of a class derived from ios_base (generally an output stream object). It is only used to obtain formatting information.

fill

Fill character: The fill character is used in output insertion operations to fill spaces when results have to be padded to the field width.
Member type char_type is the facet's character type (defined as an alias of num_put's first template parameter, charT).

val

Value to be formatted.

int main ()
{
  std::cout.width(10);    // set field width to 10 characters

    (std::cout, std::cout, '0', 3.14159265);

  std::cout << '\n';

  return 0;
}

num_get::get

Get numeric value (public member function)
