Effects: Calls str.setf(ios_base::internal, ios_base::adjustfield).
Returns: str.
ios_base& left(ios_base& str);
Effects: Calls str.setf(ios_base::left, ios_base::adjustfield).
Returns: str.

Effects: Calls str.setf(ios_base::oct, ios_base::basefield).
Returns: str.
The function signature dec(ios_base&) can be called by the function signature basic_ostream& stream::operator<<(ios_base& (*)(ios_base&)) to permit expressions of the form cout << dec to change the format flags stored in cout.
ios_base& fixed(ios_base& str);
Effects: Calls str.setf(ios_base::fixed, ios_base::floatfield).
Returns: str.
ios_base& scientific(ios_base& str);
Effects: Calls str.setf(ios_base::scientific, ios_base::floatfield).
Returns: str.
ios_base& hexfloat(ios_base& str);
Effects: Calls str.setf(ios_base::fixed | ios_base::scientific, ios_base::floatfield).
Returns: str.
[ Note: The more obvious use of ios_base::hex to specify hexadecimal floating-point format would change the meaning of existing well defined programs. C++2003 gives no meaning to the combination of fixed and scientific. — end note ]
Effects: Calls str.unsetf(ios_base::floatfield).
Returns: str.
error_code make_error_code(io_errc e) noexcept;
Returns: error_code(static_cast<int>(e), iostream_category()).
error_condition make_error_condition(io_errc e) noexcept;
Returns: error_condition(static_cast<int>(e), iostream_category()).
const error_category& iostream_category() noexcept;
Returns: A reference to an object of a type derived from class error_category.
The object's default_error_condition and equivalent virtual functions shall behave as specified for the class error_category. The object's name virtual function shall return a pointer to the string "iostream".
