Subject: [Bug libfortran/48615] Invalid UP/DOWN rounding with E and ES descriptors
Date: Sat, 23 Apr 2011 11:07:00 -0000	[thread overview]
Message-ID: <bug-48615-4-B06xUv23ih@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #2 from Thomas Henlich <thenlich at users dot sourceforge.net> 2011-04-23 11:06:28 UTC ---
The second branch (let printf do rounding) should only be choosen if the
requested rounding mode is the same as printf uses (nearest/compatible?) and
either
- the format is ES or
- the format is D, E or G; and the scale factor is 0.

I am unsure about the last requirement (scale_factor==0); isn't the number of
digits known even if the scale factor is != 0?
