\neNot Equal Sign (≠) — Copy & Paste
The not equal sign for mathematical and logical comparisons.
What does ≠ mean?
The ≠ sign means “not equal to”: the values or expressions on either side are different. For example, a ≠ b.
How ≠ differs from = and !=: ≠ states that two values are different, while = states that they are equal. In plain-text code, != is a two-character operator rather than the Unicode ≠ sign.
