That's how floating-point arithmetic works: look at the result of
2.8/0.1 to see why int() is correct.

Yes, it is known, and correct since you use "float". See

This is a link-local address, you can't use it just like that (you may
have several interfaces with the same link-local addr). Use getaddrinfo
on "FE80...%et
