U+2266 "≦" Less-than over Equal To Unicode Character

Unicode Version 17.0

U+2266 "≦" Less-than over Equal To is a mathematical symbol that vertically combines a less-than sign with an equals sign underneath, representing a relationship where one value is either less than or exactly equal to another. It is frequently used in mathematics and logic as a compact alternative to the two‑character sequence ≤, though its presentation may differ slightly across fonts. This character belongs to the Mathematical Operators block and is distinct from the more common “less‑than or equal to” symbol U+2264 ≤, as “≦” emphasizes the stacking of the two operators. In some contexts, especially in Japanese and Chinese mathematical notation, “≦” can carry a nuance of “less than but also possibly equal to,” mirroring the visual order of the symbols.
