DescriptionThe Unicode character ⅘, or U+2158, is named "Vulgar Fraction Four Fifths". It is part of the "Number Forms" block, which includes characters that represent numbers in various unusual forms. This character falls under the "Number, Other" category. Visually, it represents the fraction four-fifths (4/5) as a single glyph, with the number four (the numerator) above the number five (the denominator). The term "vulgar" in its name refers to the traditional name for common fractions, not the modern sense of the word as meaning coarse or crude. This compact representation of fractions is often used in mathematical, scientific, or technical texts, where space is a consideration, and where it is preferable to avoid the horizontal fraction bar that is typically used in computer typesetting. Its specific usage can depend on its context.
