Infinity infinity. The symbol is encoded in Unicode at and in LaTeX as codice_1. It was introduced in 1655 by John Wallis, and, since its introduction, has also been used outside mathematics in modern mysticism and literary symbology. Leibniz, one of the co-inventors of infinitesimal calculus, speculated widely about infinite numbers and their use in mathematics.

In real analysis, the symbol formula_1, called "infinity", is used to denote an unbounded limit.
