ASCII Character ½
Fraction one halfIn computer displays and typography, simple fractions are sometimes printed as a single character, e.g. ½ (one half), with roughly the same height and width as other characters in the text. Generally used for simple fractions, such as: ½, ⅓, ⅔, ¼, and ¾. Since the numerals are smaller, legibility can be an issue, especially for small-sized fonts. These are not used in modern mathematical notation, but in other contexts.
