Tiny nitpick, but I assume you mean approximately, not proportionally here

[pradyunsg]

~ stands for "around" here.

[CAM-Gerlach]

For some historical background, ≈ is the approximate symbol; ~ (tilde) was originally intended and used as a diacritic intended for overprinting over other letters for non-Latin characters, but historically was used informally for (among other purposes) an approximation (heh) of the actual approximate symbol before Unicode existed. And of course, when writing shorthand notes, its faster to type than an alt/option code.

I never knew ~ can mean proportionally, but it's widely understood as around/about/approximately, let's keep it simple :)

≈ seems more of a mathematical thing.

I don't think I've ever seen ≈ used as a unary operator.
In formal writing this would be spelled out, in a proper mathematics text the operator would be defined. But these are shorthand notes.

≈ is unusual and thus slightly harder to read for me personally (though I can type it just fine), and the suggestion is a “tiny nitpick” in notes, so I'll take the liberty to merge without it.
But feel free to continue the discussion if you want.
