: Might not work on other machines, though.  (I honestly don't know,
: I've never used a machine that wasn't 2's-complement)

One's complement works as well:
+0 = 0x00000000 (lowest bit not set)
-0 = 0x80000000 (lowest bit not set)
-1 = 0x80000001 (lowest bit set)
-2 = 0x80000002 (lowest bit not set)

What other interesting representations are there?
