There was a problem hiding this comment.
thanks @marenwestermann , this looks right
pandas/pandas/core/internals/blocks.py
Line 1511 in d831326
and numpy documents it as rounding to the nearest even value. likewise pyarrow https://arrow.apache.org/docs/python/generated/pyarrow.compute.round.html

doc/source/whatsnew/vX.X.X.rstfile if fixing a bug or adding a new feature.Description:
In the pandas documentation it is not documented how numbers are rounded if values are exactly halfway between rounded decimal values (they are rounded to the nearest even value). I added the documentation for this behaviour.
