As an aside, historically many of the early binary computers used ones complement. So they had both -0 and +0 integers as well. While ones complement is probably more obvious than twos complement, it was near-universally considered a terrible mistake by the mid-1960s, and everything of note since has been twos complement. It didn't die quickly though. The UNIVAC is still with us (in emulation) and that is likely the reason why the C standard addresses the question of negative zero integers. (Their handling is implementation specific, of course.)
