New submission from David MacIver:
The following code produces an OverflowError:
import statistics
statistics.mean([8.988465674311579e+307, 8.98846567431158e+307])
The error is:
File "/home/david/.pyenv/versions/3.5.0/lib/python3.5/statistics.py", line
293, in mean
return _sum(data)/n
File "/home/david/.pyenv/versions/3.5.0/lib/python3.5/statistics.py", line
184, in _sum
return T(total)
File "/home/david/.pyenv/versions/3.5.0/lib/python3.5/numbers.py", line 291,
in __float__
return self.numerator / self.denominator
OverflowError: integer division result too large for a float
If this is intended behaviour then it is not documented:
https://docs.python.org/3/library/statistics.html#statistics.mean only
specifies that it may raise StatisticsError.
