#
Each function specified in this subclause is a designated addressable function ([namespace.std]).
🔗
ios_base& fixed(ios_base& str);
2
#
Effects: Calls str.setf(ios_­base​::​fixed, ios_­base​::​floatfield).
3
#
Returns: str.
🔗
ios_base& scientific(ios_base& str);
4
#
Effects: Calls str.setf(ios_­base​::​scientific, ios_­base​::​floatfield).
5
#
Returns: str.
🔗
ios_base& hexfloat(ios_base& str);
6
#
Effects: Calls str.setf(ios_­base​::​fixed | ios_­base​::​scientific, ios_­base​::​floatfield).
7
#
Returns: str.
8
#
[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.
