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.
