What algebra uses negative 0?
IEEE 754
I mean it's an algebra, isn't it? And it definitely was mathematicians who came up with the thing. In the same way that artists didn't come up with the CGI colour palette.
I'm not familiar with IEEE 754.
Edit: I think this sort of space shouldn't be the kind where people get downvoted for admitting ignorance honestly, but maybe that's just me.
IEEE 754 is the standard to which basically all computer systems implement floating point numbers. It specifically distinguishes between +0 and -0 among other weird quirks.
