Antoine Pitrou commented on ARROW-2856:
---------------------------------------
This is consistent with Numpy behaviour. I would expect PyArrow to not be
stricter than Numpy here:
{code:python}
>>> np.int8([1.1])
array([1], dtype=int8)
{code}
> [Python/C++] Array constructor should not truncate floats when casting to int
> -----------------------------------------------------------------------------

> 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>
> [
