Yes. An alternate solution would be

  cout.setf(ios_base::fmtflags(0), ios_base::floatfield)

Well, I may be wrong, but in the _final_ standard I cannot find examples 
of a 'plain' 0 but always ios_base::fmtflags(0). Otherwise, make use of 
what I replied earlier today.

Barring any additional clarification on the '0' vs ios_base::fmtflags(0) 
issue, I would close the PR.

Ciao, Paolo.
