≄

not asymptotically equal to

Not Asymptotically Equal To

≄ says two functions or sequences do not become equivalent in the stated limit. With the usual ratio definition, their quotient does not tend to 1; the slash negates ≃.

What ≄ means

It says the expressions fail the asymptotic relation ≃. In the usual ratio definition, their quotient does not tend to 1 as the variable approaches the limit in question.

This denies a particular limiting relationship; it does not mean the expressions differ at every input. Unicode represents the negation by overlaying ≃ with a combining long solidus.

Formal mathematical notation for denying asymptotic equivalence in a formula or proof.

Use ≠ for ordinary inequality at a value; ≄ denies a limiting relationship.

≃
Asymptotically Equal To
The positive asymptotic-equivalence relation; ≄ denies it.
≈
Almost Equal To
Usually means almost or approximately equal, without specifying a limiting relationship.
≠
Not Equal To
Ordinary inequality at a value; it says nothing about limiting behavior.

Why does ≄ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
