(In reply to Joseph Myers from comment #1)
> Floating-point addition is how ISO C defines FLT_ROUNDS.=20=20

Can be, but think the mode is affecting other operations too.=20=20
If ISO C used a 'simple' misleading definition it need=20=20
not spread further. The mislead is that it injects the idea=20=20
of different rounding modes for different operations.=20=20

don't understand the connection, nor the other bug at all.=20=20
Think I can change the rounding mode with fesetround, also=20=20
at runtime, needs other parameters but works.=20=20

The bug was only about 'addition' vs. 'operation'.
