Antoine Pitrou commented on ARROW-3329:
---------------------------------------
It works here:
{code}
>>> arr = pa.array([Decimal("1234")], type=pa.decimal128(19,10))
>>>
>>>
>>> arr
>>>
>>>
<pyarrow.lib.Decimal128Array object at 0x7efbbeadea60>
[
1234.0000000000
]
>>> arr.cast(pa.int16())
>>>
>>>
<pyarrow.lib.Int16Array object at 0x7efbbeadec20>
[
1234
]
{code}
[~jacek.pliszka] I assume you want to add some tests? Or is it something else?
