Hi Eop,

Just go thru all the float point FRM intrinisc API and locate some of them that may need double confirmation with you, for the FRM is honored or not.

CC @kito-cheng and @zhongjuzhe for awareness.

I think vf(w)redsum uses rounding mode. The others do not.

Incarnation-p-lee commented 1 year ago

Yes, vfw from INT to FP may never lose precisions, thus rounding is not required up to a point.

Floating-point rounding mode intrinsics are added now. Closing this issue.
