ios_base& fixed(ios_base& str);
1
#

Effects: Calls str.setf(ios_­base​::​fixed, ios_­base​::​floatfield).

2
#

Returns: str.

ios_base& scientific(ios_base& str);
3
#

Effects: Calls str.setf(ios_­base​::​scientific, ios_­base​::​floatfield).

4
#

Returns: str.

ios_base& hexfloat(ios_base& str);
5
#

Effects: Calls str.setf(ios_­base​::​fixed | ios_­base​::​scientific, ios_­base​::​floatfield).

6
#

Returns: str.

7
#

[ 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 ]

ios_base& defaultfloat(ios_base& str);

8
#

Effects: Calls str.unsetf(ios_­base​::​floatfield).

9
#

Returns: str.
