[jira] [Created] (ARROW-5514) [C++] Printer for uint64 shows wrong
values
Joris Van den Bossche created ARROW-5514:
--------------------------------------------
Summary: [C++] Printer for uint64 shows wrong values
Key: ARROW-5514
URL: https://issues.apache.org/jira/browse/ARROW-5514
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 0.13.0
Reporter: Joris Van den Bossche
From the example in ARROW-5430:
{code}
In [16]: pa.array([14989096668145380166, 15869664087396458664], type=pa.uint64())
Out[16]:
<pyarrow.lib.UInt64Array object at 0x7ff7c51bdf48>
[
-3457647405564171450,
-2577079986313092952
]
{code}
I _think_ the actual conversion is correct, and it's only the printer that is going wrong, as {{to_numpy}} gives the correct values:
{code}
In [17]: pa.array([14989096668145380166, 15869664087396458664], type=pa.uint64()).to_numpy()
Out[17]: array([14989096668145380166, 15869664087396458664], dtype=uint64)
{code}
