An overline, overscore, or overbar, is a typographical feature of a horizontal line drawn immediately above the text. In old mathematical notation, an overline was called a vinculum, a notation for grouping symbols which is expressed in modern notation by parentheses, though it persists for symbols under a radical sign.
In 1637 Descartes was the first to unite the German radical sign √ with the vinculum to create the radical symbol in common use today. [8] The symbol used to indicate a vinculum need not be a line segment (overline or underline); sometimes braces can be used (pointing either up or down). [9]
The overline is a typographical symbol similar to the macron, used in a number of ways in mathematics and science. For example, it is used to represent complex conjugation : z = a + b i ; z ¯ = a − b i {\displaystyle z=a+bi;\quad {\overline {z}}=a-bi}

Unicode included the most common blackboard bold letters among the "Letterlike Symbols" in version 1.0 (1991), inherited from the Xerox Character Code Standard. Later versions of Unicode extended this set to all uppercase and lowercase Latin letters and a variety of other symbols, among the "Mathematical Alphanumeric Symbols". [19]
