#
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 1: 
ios_base​::​hex cannot be used to specify a hexadecimal floating-point format, because it is not part of ios_base​::​floatfield (Table 119).
