The command-line interpreter, cmd.exe, of Windows uses the circumflex to escape reserved characters (most other shells use the backslash). Often seen as caret notation to show control characters, for instance ^A means the control character with value 1. The upward-pointing arrow is now used to signify hyperoperations in Knuth's up-arrow notation.

As Isaac Asimov described it in his 1974 ' Skewered!' essay (on Skewes' number), 'I make the exponent a figure of normal size and it is as though it is being held up by a lever, and its added weight when its size grows bends the lever down.' The use of the circumflex for exponentiation can be traced back to ALGOL 60, which expressed the exponentiation operator as an upward-pointing arrow, intended to evoke the superscript notation common in mathematics. It is also used to indicate a superscript in TeX typesetting. In mathematics, the circumflex can signify exponentiation ( 3^5 for 3 5), where the usual superscript is not readily usable (as on some graphing calculators). Surrogate symbol for superscript and exponentiation

In the case of Node.js, a circumflex allows any kind of update, unless it is seen as a 'major' update as defined by semver. Node.js uses the circumflex in package.json files to signify dependency resolution behavior being used for each particular dependency.

In Apple's C extensions for Mac OS X and iOS, circumflex are used to create blocks and to denote block types. NET reference types are accessed through a handle using the ClassName^ syntax. In Smalltalk, the circumflex is the method return statement. Pascal uses the circumflex for declaring and dereferencing pointers. RFC 1345 recommends to transcribe the character as digraph '> when required. In regular expressions, the circumflex is used to match the beginning of a string or line if it begins a character class, then the inverse of the class is to be matched.ĪNSI C can transcribe the circumflex in the form of the trigraph ?', as the character was originally not available in all character sets and keyboards.Ĭ++ additionally supports tokens like xor (for ^) and xor_eq (for ^=) to avoid the character altogether. It can signify exponentiation, the bitwise XOR operator, string concatenation, and control characters in caret notation, among other uses. The free-standing circumflex symbol ^ has many uses in programming languages, where it is typically called a caret. This circumflex is not to be confused with other chevron-shaped characters, such as the circumflex accent, the turned v or the logical AND, which may occasionally be called carets. This symbol is often called a 'caret', but this page will call it a 'circumflex' to distinguish it from a true caret. The character became reused in computer languages for many other purposes, and over time its appearance was enlarged and lowered, making it unusable as an accent mark. The symbol was included in typewriters and computer printers so that circumflex accents could be overprinted on letters (as in ô or ŵ). There is a similar mark, ^, that has a variety of uses in programming, mathematics and other contexts. The caret ( / ˈ k ær ɪ t/) is a V-shaped grapheme, usually inverted and sometimes extended, used in proofreading and typography to indicate that additional material needs to be inserted at this point in the text.
