What does an "equal" sign with three lines instead of the standard = (2) mean?

?

Equivelency, I believe.

 

[Zenmervolt]

IIRC, that symbol means, "is defined as".

Isn't that congruency?

 

[tweakmm]

are you sure it's not an equal sign with a squigly line above it?

 

[Moonbeam]

Some equals are more equal than others.

It's the standard sign for congruency in modular arithmetic, if that's what setting you are in. := is "defined as" in most math software.

Nope.

"Identically equal to," if I remember correctly.

 

[yoda291]

it means whatever is on the left will always equal what is on the right I think.

 

[Soccer55]

Depending on the context it's either "congruent to" or "identically equal to". It's mainly used as "congruent to" when dealing with modular arithmetic.

Thanks all!

Maybe like = versus == in programming/scripting?

 

[Jzero]

IT means like REALLY freaking equal.
😉

i think that only applies in non-mathematic situations though 😉

This is right...well, whenever I've seen it used recently, but I have seen it used in other terms too. But this is the one I see most commonly in physics and calc.
