Actually I was envisioning that one would just add the desired facet
after the stream was created.  I don't see that this would require
any new stream flags or manipulators.  Something like

// make a new locale
std::locale float_locale(std::locale::global(),  new 
codecvt_strict_float());
fostream os("filename");
os.imbue(float_locale);

//... operations on os use fixed or strict floating point output
