[BUG] About the rounding mode of TF32

[beginlner]

https://github.com/NVIDIA/cutlass/blob/main/include/cutlass/tfloat32.h#L80
Why does the code represent "round toward nearest even", but not "round to nearest, ties away from zero"?

[hwu36]

I don't fully understand your questions. Exactly as this rounding method says, it "round_half_ulp_truncate", so it is not "to the nearest even"

we do this because it only takes two instructions to do the conversion.
