There’s probably a better way, but:
[0xFFFFFFC4].pack(“l”).unpack(“l”)[0] # => -60

I definitely wouldn’t have stumbled on that for a while 
Guess I’ll have to check the doc to figure out what’s going on there, but in
the meantime it works!
Thanks a lot,

The pack takes a Fixnum and converts it to a String of 4 bytes which
represents the value (“l” means long). Then, we unpack the 4 bytes
as a signed long back into a Fixnum. “L” would be unsigned.
#pack and #unpack are incredibly powerful.
