I just copied this code from PyArg_ParseTuple*() for 'l' format.

Any C implemented function which parses an integer argument with PyArg_ParseTuple*() accepts decimals.

>>> chr(65.2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: integer argument expected, got float
>>> chr(Decimal('65.2'))
'A'

I think this is an offtopic for this issue.
