Okay but raster images can't represent circles either, since they're just approximations using squares

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

And many "circles" aren't circles either, but 2D torus approximations. The edge of a true circle is made of infinitesimally small points so would be invisible when drawn. And even if you consider a filled circle, how could you be sure you aren't looking at a 1-torus with an infinitessimally small hole? Or an approximation of all the set of all points within a circle?
Clearly, circles are a scam.
A 1-torus is a circle, you mean an annulus. You do NOT want to make this mistake at a topologist dinner party, trust me.
Damn, so what's the name of the shape that's a flat donut with an inner and outer circular perimeters? i.e. a filled circle with another smaller radius circular area subtracted from it. Or 2D cross section of a torus seen perpendicularly to the plane that intersects the widest part of the torus. A squished donut, or chubby circle, if you like.
Annulus
Hah he said annulus
They overly annulus to me.
Damn you PDF, damn you to heck!

Well I'd argue vector image can represent a real circle but what's on the screen will never be one.
Also why is this on Lemmy Linux?
There are analog vector displays.
Ah yes indeed but there must be some imperfections down the line so not a Real circle, though we are getting closer.
In this sense, we don't have real rectangles or lines, either
So what I'm learning is nothing is real...
It's all cake.
