![]() For instance to pass a less-than sign as an argument to a program you type ^<. 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. C++ additionally supports tokens like xor (for ^) and xor_eq (for ^=) to avoid the character altogether. 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. 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. Remember, you should toggle Unicode Hex Input for using these alt code shortcuts.Caret telling reader to change a word. For example, option and 2016 keys to type pipeline symbol like ‖. On Mac documents like Pages, press alt or option key and type the Mac code. For example, press 22EE then alt and x keys to type vertical ellipsis symbol like ⋮. Alternatively, on Word documents, you can use the hexadecimal code in the second column with alt and X keys.For example, Alt + 8263 will produce double question mark symbol like ⁇. ![]() On Windows documents, you can hold one of the alt key on your keyboard and press the code using number pad.Heavy Right Single Turned Comma Quotation Heavy Left Single Turned Comma Quotation Mark ![]()
