Pandas version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of pandas.

  • I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import numpy as np
import pandas as pd

s = pd.Series([10000000000000000000], dtype="uint64")
s.sum()  # -8446744073709551616
s.to_numpy().sum()  # 10000000000000000000

s = pd.Series([10000000000000000000], dtype="uint64[pyarrow]")
s.sum()  # 10000000000000000000

Issue Description

The summation of a series of uint64 is converted to int64.

Expected Behavior

The result would be a uint64.
