INFINITY
Overview
∞, the INFINITY symbol, represents the mathematical concept of a quantity without bound. Encoded at U+221E in the Mathematical Operators block, it is classified as a mathematical symbol and written in HTML as ∞. Its familiar sideways-figure-eight form is used in calculus to describe limits and unbounded ranges, and beyond mathematics it serves as a general emblem of endlessness, one of the most recognizable abstract symbols in the Unicode repertoire.
