Comment (by pbristow):

 Well this looks a bit more complicated than I feared.  There seems to be a
 difference between sending to cout (00000) and a stringstream (00.00).


 {{{
  cout << std::fixed << std::setw( 5 ) << std::setfill( '0' ) <<
 std::setprecision( 2 ) << 0.0 << endl; // 00000

   std::stringstream astream;
   astream << std::fixed << std::setw( 5 ) << std::setfill( '0' ) <<
 std::setprecision( 2 ) << 0.0; // 00.00
 }}}

 which leaves me more than a bit wary of making any precipitate changes to
 Johan Rade's nonfinite_num_put code :-(  (Before fools step in where
 angels fear to tread? - again!)

 I'd like you to consider if it might be safer to circumnavigate this
 'feature'?
