We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
`around` result is different compared to numpy
```
>>> np.__version__
'1.16.4'
>>> np.around([2.5])
array([2.])
>>> cupy.__version__
'7.0.0a1'
>>> cupy.around([2.5])
array([3.])
```
NumPy seems to round to even.
