Hi Hans, If I understand corretly, #13 is a potential problem arising from a change in behavior, not an argument in favor of one rounding mode vs another per se.
The only reasonably cogent argument I know is mentioned in #8750 (unbiasedness). I am glad that the issue is now closed, since that means no more electrons are wasted on it, but I am still curious about practical examples where rounding mode makes a difference in numerical code. All I have seen rely on ill-conditioning, which is a separate issue.
