Summary: Decimal.__int__ overflows for large values
Initial Comment:
This also affects Decimal.__hash__, since it [indirectly] calls Decimal.__int__.
>>> from decimal import Decimal as D
>>> e = D("1e1234567890987654321")
>>> int(e)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/decimal.py", line 1501, in __int__
s = ''.join(map(str, self._int)) + '0'*self._exp
OverflowError: cannot fit 'long' into an index-sized integer
>>> e = D("1e1234567890")
>>> int(e)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/decimal.py", line 1501, in __int__
s = ''.join(map(str, self._int)) + '0'*self._exp
MemoryError
Also, for values that do work this is incredibly slow if they are still fairly
large.
