I should have checked the issues on github before mailing the list:

[Numpy-discussion] TypeError when multiplying float64 and a big integer in Python 3.

2013-06-16 Thread Warren Weckesser 
With Python 3.3.2 (64 bit), and numpy master:

>>> import numpy as np
>>> np.__version__
'1.8.0.dev-2a5c2c8'

>>> f = np.float64(1.0)
>>> i = 2**65
>>> f*i
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unsupported operand type(s) for *: 'numpy.float64' and 'int'

Is this the expected behavior?

The error does not occur with integers that fit in 64 bits:

>>> f*10
10.0

It also does not occur in numpy 1.7.1.
