The use of hyphens as a substitute for dashes is substandard in English Wikipedia; see MOS:HYPHEN. The hyphen-minus is used as a minus sign in computer programming languages, and in math mode, but in text, the proper typographical symbol for negation or subtraction is the minus sign, available in the "Special characters" dropdown of the edit ...
In some styles, minus signs are represented using an en dash instead of a minus sign or a hyphen. This is not done in Wikipedia. In math formulas a hyphen-minus codes for a minus sign, but in text − produces the minus sign (see below). En dash ("–", MOS:ENDASH) are slightly longer than hyphens. They are used:
The hyphen-minus symbol -is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash so it is also used for these. [1] The name hyphen-minus derives from the original ASCII standard, [2] where it was called hyphen (minus). [3]
The hyphen-minus symbol (-) is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash so it is also used for these. [27] The name hyphen-minus derives from the original ASCII standard, [28] where it was called hyphen–(minus). [29]
The hyphen ‐ is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation. [1]The hyphen is sometimes confused with dashes (en dash –, em dash — and others), which are wider, or with the minus sign −, which is also wider and usually drawn a little higher to match the crossbar in the plus sign +.
A function f is even if and only if f(−x) = f(x) for all x; write A function f is even if f(−x) = f(x) for all x. If it is reasonable to do so, rephrase the sentence to avoid the use of the word "if" entirely. For example, An even function is a function f such that f(−x) = f(x) for all x
The hyphen, minus sign, and dashes of various widths have been collapsed into a single character (-), sometimes repeated to represent a long dash. The spaces of different widths available to professional typesetters were generally replaced by a single full-character width space, with typefaces monospaced .
This essay explains use of the non-breaking hyphen character ‑, U+2011, coded by ‑ or ‑. Once displayed in a page, the non-breaking hyphen can be copied into words, or abbreviations, so they will not wrap at the hyphen character, such as an interstate highway symbol, "I‑94", which would always wrap to the next line as a whole word.
