BUG: Results of series bitwise ufunc operations are being casted to bool in pandas-2.0 · Issue #52500 · pandas-dev/pandas (original) (raw)

Pandas version checks

Reproducible Example

In [1]: import pandas as pd

In [2]: import numpy as np

In [3]: np.bitwise_xor Out[3]: <ufunc 'bitwise_xor'>

In [4]: a = pd.Series([1, 2, 3], index=[10, 11, 23], name="a")

In [5]: b = pd.Series([10, 20, 30], index=[11, 10, 23], name="a")

In [9]: np.bitwise_xor(a, b) Out[9]: 10 True 11 True 23 True Name: a, dtype: bool

In [10]: np.bitwise_xor(a.to_frame(), b.to_frame()) Out[10]: a 10 21 11 8 23 29

Issue Description

bitwise_xor on Series & DataFrame are returning different results(i.e., bool & int respectively).

Expected Behavior

Consistent output between Series & DataFrame:

In [9]: np.bitwise_xor(a, b) Out[9]: 10 21 11 8 23 29 Name: a, dtype: int64
