@aschade : Thanks for submitting this!  Quick question: any reason why you submitted a new PR?
@gfyoung the other branch got out of sync so I just made a clean one
@aschade you can simply merge master or rebase and force push to keep up to date

@jreback Ok will do next time
The Series tests pass for me locally but on AppVeyer they're failing since the operations are casting the Series' `dtype` to `int32` and on my local machine they're `int64`. Not really sure how to debug this since I can't reproduce locally.
