I like your point here. I think 1/0 = Infinity+ is a satisfying expression. Its a clear concept which can be visualized in a simple graph.
I think 0/0 is a different concept than 1/0. It's a different expression. 0/0 doesn't explicitly express a particular "path" on the graph.
We can call it (0/0) different names if we want. They can say 0/0 = "undefined". I am currently satisfied with 0/0 simply equals to 0/0, or simply "undefined".
If we all agree it is "undefined" we ironically defined it.

It still depends on which side you take the path from - from the positive denominator or the negative denominator side. (This is why IEEE 754 has a single signless infinity).
- anoplus 8y agoOpps, I forgot the negative side. Thanks.
- jibal 8y ago> IEEE 754 has a single signless infinity No it doesn't. I don't know where you got that idea, but it can't be from ever writing any floating point code, or looking at the IEEE-754 standard, or the floating point format. Please see https://www.h-schmidt.net/FloatConverter/IEEE754.html https://www.h-schmidt.net/FloatConverter/IEEE754.html and stop spreading radically wrong misinformation. > It still depends on which side you take the path from - from the positive denominator or the negative denominator side. In IEEE-754, 1/0 == Infinity and 1/-0 == -Infinity.
- ummonk 8y agoDon't know why you're getting downvoted, but thanks for the clarification. Looks like I misremembered. Apparently it also has +0 and -0...
