### Describe the bug, including details regarding any error messages,
version, and platform.
I am trying to write a structured data using the following schema.
Using pyarrow==13.0.0
on a MacOS Monterey 12.1, M1 macbook
It seems like, that above a certain value, a floating point number is
written incorrectly to the resulting parquet file. The error seems to depend on
the actual value of the number.
This is the minimum code where I could replicate this behaviour:
```python
import pandas as pd
import pyarrow as pa
schema = pa.schema(
[
pa.field(
name="root",
type=pa.struct(
[
pa.field(name="timestamp", type=pa.float32(),
nullable=True),
]
),
nullable=True,
)
]
)
def test_pyarrow_write_bug():
data = [
{'root': {'timestamp': 1.0}},
{'root': {'timestamp': 1693260000.0}},
{'root': {'timestamp': 846630000.0}},
{'root': {'timestamp': 423315000.0}},
{'root': {'timestamp': 211657500.0}},
{'root': {'timestamp': 105828750.0}},
{'root': {'timestamp': 52914375.0}},
{'root': {'timestamp': 26457187.0}},
]
df = pd.DataFrame(data)
table = pa.Table.from_pandas(df, schema=schema)
pa.parquet.write_table(table, 'test_pyarrow_write_bug.parquet')
df_read = pd.read_parquet('test_pyarrow_write_bug.parquet')
assert df['root'].to_list() == df_read['root'].to_list()
```

I would expect the written and read files
