Then how do you numerically describe the concept of infinitely close proximity to an integer without being quite there?

Y'know the thing about a shitbull, he's got... lifeless eyes, black eyes, like a doll's eyes. When he comes at ya, doesn't seem to be livin'... until he bites ya. And those black eyes roll over white, and then... oh, then you hear that terrible high-pitch screamin', the pavement turns red, and n’spite of all the poundin' and the hollerin', they all come in and they... rip you to pieces.

there's a difference between the limit and the value at the end, example

1^ \infty ~~~ undefined

>asymptote - a line that continually approaches a given curve but does not meet it at any finite distance.
The definition of asymptote says you're wrong. It is at least equally conceivable, as a number can be so infinitely close that it jumps magically to being the next number, that a number is just that -- infinitely close

It's called an asymptote.
You can graph both infinitely small and infinitely big numbers with an asymptote as a limit for both ends of the graph.
Ways to visualise an asymptote is with the charging if a capacitor, as the cap charges the potential difference decreases, slowing the charging of the cap, as the cap approaches its maximum voltage charging slows infinitely, but never reached the charging current.
The cha going current is the limit, or max, so imagine so say 1 volt.
So charging from a 1 volt power source, to a 1 volt cap, the cap never reaches 1,

This exact same maths can be used to graph the discharge of a cap ;) as the discharge limit is now 0 volts.

An asymptote lies at both 1, and 0, and 0 and 1 are the limits of the range of the graph.

So before you try to convince me a capacitor charged to 0.00999. volts is actually 1 volt (impossible), maybe learn some maths like limits and asymptotes first.

You need to learn the difference between higher/abstract maths/physics and "real world/applied maths and physics.

This 0.999...=1 thing is vectored maths.

Easy. 0.999...= 1
Just take the last 9 and turn it into an 8 and that number is then infinitely close to 1
