Aren't declared yet in std the

                               hexfloat
                               defaultfloat

C++11 manipulators?

It is planned to introduce them?

I ask this because the statement

           std :: cout << 0x1.8p-1 << std :: endl;

is recognized by the 4.8.3 release of the gcc/g++ compiler and prints 
out (correctly) 0.75 while the "opposite"
(which I argued could print 1.8p-1)

           std :: cout << std :: hexfloat << 0.75 << std :: endl;

is considered erroneous: the compiler claims hexfloat being not declared 
(all reasonable headers were been included).

Thanks

Yes, there is a patch from earlier this year (see the libstdc++ list
archives) that still needs to be applied.

It's on my TODO list.
