The equal sign with three lines means that something is identical or similar to something but not necessarily equal. Thus, a triple equals sign means equivalent. The equivalent is not the same as 'equals'.


What does ≡ mean in math?

≡ means identical to. This is similar to, but not exactly the same as, equals. Therefore, if in doubt, stick to =. ≈ means approximately equal to, or almost equal to. The two sides of a relationship indicated by this symbol will not be accurate enough to manipulate mathematically.

What does =~ mean in math?

The Unicode standard lists all of them inside the Mathematical Operators Block. ≈ : ALMOST EQUAL TO (U+2248) ≃ : ASYMPTOTICALLY EQUAL TO (U+2243) ≅ : APPROXIMATELY EQUAL TO (U+2245)

What is the difference between double == and triple === equals?

Double Equals ( == ) checks for value equality only. It inherently does type coercion. This means that before checking the values, it converts the types of the variables to match each other. On the other hand, Triple Equals ( === ) does not perform type coercion.
