Comment:

 This is intentional. Integers operated with integers should return
 integers. Unfortunately, there is no integer infinity that we can use. By
 default in 1.0.3 (at least) we print a warning.

 {{{

 In [1]: from numpy import *

 In [2]: 1/int_(0)
 Warning: divide by zero encountered in long_scalars
 Out[2]: 0

 }}}

 You can change this to raise an error or silence the warning using the
 {{{seterr()}}} function.
