Unpacking the ≶ (Less-Than or Greater-Than) Symbol
The ≶ symbol, officially named "Less-Than or Greater-Than," is a mathematical operator used to indicate that one value is strictly unequal to another. By stacking the standard less-than (<) and greater-than (>) signs, it visually represents a relationship where two items can be either smaller or larger, but never identical. In mathematics and order theory, it serves as a highly specific alternative to the standard "not equal" (≠) sign.
The Unicode standard assigns ≶ the code point U+2276. You will find it housed within the Mathematical Operators block, a massive collection of characters designed to standardize complex mathematical, logical, and scientific notation across global operating systems.
In practical mathematics, ≶ emphasizes strict inequality within a defined sequence. While the standard ≠ symbol simply means "different" (which could apply to colors, shapes, or non-ordered concepts), ≶ highlights that the numbers exist on a continuous scale where one physically falls above or below the other. In programming, the visual concept of ≶ translates to the typed <> operator. Developers use <> in languages like SQL, Visual Basic, and Pascal to trigger a "not equal to" logic check. Outside of STEM environments, typography enthusiasts occasionally repurpose the ≶ character in text art or social media formatting for its perfectly balanced, geometric aesthetic.
Typing the ≶ symbol requires specific shortcuts depending on your operating system. Windows users can type "2276" in Microsoft Word and immediately press Alt + X to convert the code into the symbol. Mac users with the Unicode Hex Input keyboard active can hold the Option key and type 2276. For web developers, dropping the HTML entity ≶ or ≶ into your code will render the symbol flawlessly in any modern browser. Academic writers using LaTeX can simply type the \lessgtr command to insert it directly into their formulas.
The ≶ symbol closely relates to several other inequality characters. Its direct counterpart is ≷ (Greater-Than or Less-Than, U+2277), which carries the exact same mathematical meaning but reverses the vertical order of the arrows. You will also see it compared to ≠ (Not Equal To, U+2260) and ≨ (Less-Than but Not Equal To, U+2268). While these symbols all deal with values that do not match, ≶ distinctly reminds us that those values belong to a strict, measurable order.
