@futurebird is this about IEEE 754 floating points? :)

@futurebird Just represent adding and subjacting one as base-level unary operators and let zero be the sole numeric value. Optionally let the language be lazy so that rounding issues can be postponed until the last possible moment.

@futurebird I recently came across https://github.com/tc39/proposal-math-sum , a proposal to add the "sum of this array" function to JavaScript. To my delight, it includes the absolutely correct observation that the sum of the empty list of floating-point numbers must be... -0.Because IEEE floating point representation has both +0 and -0, and x + (-x) is the normal one, +0. Which means that +0 + -0 is also +0, and that means that only -0 is the additive identity 🤯

@futurebird In binary, obviously positive zero, the sign bit is clear so zero is positive.In balanced ternary, true zero for the win.

@futurebird I like the calculus, and it doesn’t really work without positive and negative numbers which are exactly equal to zero (infinitesimals).

@mightybigcar @petealexharris @futurebird IEEE floats have positive and negative zero. The standard specifies, however, that they should compare as equal.

@futurebird @mightybigcar @petealexharris I think it's a requirement for languages/ hardware that claims to implement the standard.

@futurebird I actually see -0 show up in some things (particularly things with touchscreen sliders. I hate sliders so much...)I hate it so much. I want to fix it, but I've seen at least one that wouldn't. It goes from -0 to 1. *Rips out hair*

@futurebird Please ignore one vote for pos. zero. I clicked it while scrolling, because I‘m feeling slightly more positive than yesterday but still pretty close to zero. But I guess that‘s not what this vote is about 😊

@futurebird the sequel to Godzilla Minus One is apparently going to be titled Godzilla Minus Zero, so I suppose Godzilla has weighed in.
