Difference between "≈", "≃", and "≅" - Mathematics Stack Exchange
The approximation sign "≈" I use for decimal approximations with tilde "~" being a rougher approximation. Tilde "~" I use to state a geometric shape is similar to another one ie a triangle of sides 3/4/5 is similar to a triangle with sides 30/40/50.

logic - what is the difference between ≈ and ≃? - Mathematics …
There is no universally accepted notation, but $\approx$ and $\simeq$ both generally mean "approximately equal to." However $\simeq$ is sometimes used to denote "is similar," for instance that two triangles are similar ($\triangle ABC \simeq \triangle DEF$). You would rarely, if ever, use $\approx$ in that situation.

2018年1月12日 · $\begingroup$ I think normally authors will add a "$\ldots$" to the quantity on the right to indicate that it is exactly equal to the left side, but not exactly equal to $0.0588$, instead of weakening the sense of equality. $\endgroup$ –

2015年8月12日 · To indicate approximate equality, one can use ≃, ≅, ~, ♎, or ≒. I need to indicate an approximate inequality. Specifically, I know A is greater than a quantity of approximately B. Is there a way to
Use of approximation sign - Mathematics Stack Exchange
2017年8月2日 · I have a question regarding the placement of the almost equal to sign in relation to the equal to sign. For example, can I write: $$129{.}87\cdot 6\approx 130 \cdot 6 = 780 $$ or is it more correct to write: $$129{.}87\cdot 6\approx 130 \cdot 6 \approx 780 $$ since $129{.}87\cdot 6$ is not equal to the approximation $780$?
Equal sign or approximation sign? - Mathematics Stack Exchange
2015年6月23日 · The use of an equal sign is probably because of a bad textbook, or that the writers used it because the rounded answer is very close to the real answer. This is usually the case when the answers are off by less than $\pm \epsilon$, which is determined by the writers (usually $10^{-4}$)

Approximately not equal - Mathematics Stack Exchange
2016年2月19日 · But could it also be called “approximately less or equal” without becoming ambiguous? Unicode says “less-than or approximate”, switching from almost equal to approximate. This one is hard, I think. I could call it “not greater or approximately equal”, or I could call it “less than and not approximately equal”. The latter is more ...

2010年7月28日 · $\begingroup$ I don't see anywhere on the Wikipedia page you linked to where it recommended writing $\pi \fallingdotseq 3.14\ldots.$ It says that $\fallingdotseq$ means "asymptotically equal to," which is a different kind of approximation.
