Overflow error

[Jane Austine]

>>> from math import e
>>> e**709
8.218407461554662e+307
>>> e**710

Traceback (most recent call last):
  File "<pyshell#15>", line 1, in -toplevel-
    e**710
OverflowError: (34, 'Result too large')

What should I do to calculate e**710?

I'm using Python 2.3.4 on WinXP.
