All scales that exist in the real world are this scale, it just depends on the scale (so to speak)

Does some degree of rounding? Sure. The degree you present? I don’t want to pay for (ca) 5 pounds of meat with (ca) 4.6 pounds. And again, this is a deflection of the point of general communication/ common understanding.

Yes, I understand that you think mathematical education is just a matter of telling kids how to punch numbers into the calculator on their iPhones and that any further thought about the relationship between those abstract functions and the real world is a woke waste of time

What I am telling you is that it is your version of mathematical education that is a pointless waste of time (why the hell would anyone, even a small child, actually need me to "teach" them that "2+2=4" in the trivial sense)

And what you are doing is very much the negative form of "virtue-signaling" (setting up a strawman and tilting wildly against it)

Again: shared understanding, basic communication, the point you’re still deflecting. The degree of rounding in your scale scale would not bode well in a street market for a reason.

Hey, here's a fun thing that you understand if you actually understand math: 0.0000000002 + 0.0000000002 = 0.0000000005 isn't different from 2 + 2 = 5

This is an argument for imprecision by drilling down to a number so small we would and do round. While the same on paper, rounding || || to ||||| when each unit matters does not correspond to something acceptable in the real world where we should try to be as precise as possible.

It is not an argument "for" imprecision, it is an argument that imprecision always exists (or to rephrase, that precision is finite) You don't really know what you're talking about

It’s an argument that suggests the inevitability of imprecision makes enlargements of said imprecision okay. While on paper a small decimal and a whole number are the same, when you start translating to real units, says pizzas, one does well to be as precise as possible.

No, it is not, and you don't understand what I'm talking about
