While we're at it, what the hell is -0 and how does it differ from 0?

[–] computerscientistI@lemm.ee 2 points 1 year ago

For integers it really doesn't exist. An algorithm for multiplying an integer with -1 is: Invert all bits and add 1 to the right-most bit. You can do that for 0 of course, it won't hurt.
