Nice catch. Let me inspect it and I'll merge it soon.

So, few notes:

1. The rounding issue is from the python2 ages. Thanks for that. I believe this will fix the bug.

2. I wonder regarding the fix of the filesize-1.
   Since this issue seems to be an off-by-one issue, it might be the solution. However I'm quite baffled:
   since the bytes count goes from 0 to filesize-1 (inclusive), we cannot request byte filesize.
   For example, if we're downloading a 5 bytes file, we would request bytes 0 to 4. Requesting byte would be an error.

What do you think?

Yes you are totally right, the filesize-1 to filesize won't fix anything !

I will push a correction :)

Done

And I also round the filesize/threads in the while (threads number verification) like you said before editing your post, I think it is indeed better to check with the same chunck size we will have after
