[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 stdin, line 1, in module
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.

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