-------------------------------------

             Summary: [Python/C++] Array constructor should not truncate floats when casting to int
                 Key: ARROW-2856
                 URL: https://issues.apache.org/jira/browse/ARROW-2856
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.9.0
            Reporter: Florian Jetter


I would expect the following code to raise instead of truncating the float
{code}
In [4]: pa.array([1.9], type=pa.int8())
Out[4]:
<pyarrow.lib.Int8Array object at 0x113455e58>
[
  1
]
{code}
