odd (?) behavior: negative integer scalar in exponent

What should be the value of `2**np.int_(-32)`? It is apparently currently computed as `1. / (2**np.int_(32))`, so the computation overflows (when a C long is 32 bits). I would have hoped for it to be computed as `1./(2.**np.int_(32))`. Cheers, Alan Isaac

Looks like a bug to me. Chuck.
