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

[–] Reddfugee42 7 points 8 months ago (1 children)

It's the negative version

So it's just like 0 but with an evil goatee?

Look at the graph of y=tan(x)+ⲡ/2

-0 and +0 are completely different.

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.
