Subject: [Bug c/113455] ROUNDING: IEEE Standard: Missing decimal rounding mode 'nearest, ties away from zero' for decimalxxx datatypes.

--- Comment #3 from Joseph S. Myers <jsm28 at gcc dot gnu.org> ---
If you're linking with the version of the DFP arithmetic functions
(__bid_adddd3 etc.) in libdfp rather than the libgcc version - check the link
order carefully to make sure the right version is linked in - and they're not
respecting the rounding mode, that would be a libdfp issue, not a GCC one. If
you're doing arithmetic with constant operands, it might be folded at compile
time; make sure you're using -frounding-math to avoid that.
