MacFarsi Encoding
MacFarsi encoding is an obsolete encoding for Farsi/Persian, Urdu (and English) texts that was used in Apple Macintosh computers to texts. The encoding is identical to MacArabic encoding, except the numerals, which are the Persian/Urdu style, also known as "Extended" or "Eastern" Arabic-Indic numerals. See Arabic script in Unicode for more details.

Persian Alphabet
The Persian alphabet ( fa, الفبای فارسی, Alefbâye Fârsi) is a writing system that is a version of the Arabic script used for the Persian language spoken in Iran ( Western Persian) and Afghanistan (Dari Persian) since the 7th century after the Muslim conquest of Persia. The Persian dialect spoken in Tajikistan (Tajiki Persian) is written in the Tajik alphabet, a modified version of the Cyrillic alphabet which has been in use since the Soviet era. The Persian alphabet is directly derived and developed from the Arabic alphabet. After the Muslim conquest of Persia and the fall of the Sasanian Empire in the 7th century, Arabic became the language of government and especially religion in Persia for two centuries. The replacement of the Pahlavi scripts with the Persian alphabet to write the Persian language was done by the Saffarid dynasty and Samanid dynasty in 9th-century Greater Khorasan. The script is mostly but not exclusively right-to-left; mathematical expressi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Full Stop
The full stop (Commonwealth English), period (North American English), or full point , is a punctuation mark. It is used for several purposes, most often to mark the end of a declarative sentence (as distinguished from a question or exclamation). This sentence-ending use, alone, defines the strictest sense of ''full stop''. Although ''full stop'' technically applies only when the mark is used to end a sentence, the distinction – drawn since at least 1897 – is not maintained by all modern style guides and dictionaries. The mark is also used, singly, to indicate omitted characters or, in a series, as an ellipsis (), to indicate omitted words. It may be placed after an initial letter used to stand for a name or after each individual letter in an initialism or acronym (e.g., "U.S.A."). However, the use of full stops after letters in an initialism or acronym is declining, and many of these without punctuation have become accepted norms (e.g., "UK" and "NATO"). This trend has pro ...

Vertical Bar
The vertical bar, , is a glyph with various uses in mathematics, computing, and typography. It has many names, often related to particular meanings: Sheffer stroke (in logic), pipe, bar, or (literally the word "or"), vbar, and others. Usage Mathematics The vertical bar is used as a mathematical symbol in numerous ways: * absolute value: , x, , read "the ''absolute value'' of ''x''" * cardinality: , S, , read "the ''cardinality'' of the set ''S''" * conditional probability: P(X, Y), reads "the probability of ''X'' ''given'' ''Y''" * determinant: , A, , read "the ''determinant'' of the matrix ''A''". When the matrix entries are written out, the determinant is denoted by surrounding the matrix entries by vertical bars instead of the usual brackets or parentheses of the matrix, as in \begin a & b \\ c & d\end. * distance: P, ab, denoting the shortest ''distance'' between point P to line ab, so line P, ab is perpendicular to line ab * divisibility: a \mid b, read "''a'' ''divides'' ...

Braces (punctuation)
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket.

Grave Accent
The grave accent () ( or ) is a diacritical mark used to varying degrees in French, Dutch, Portuguese, Italian and many other western European languages, as well as for a few unusual uses in English. It is also used in other languages using the Latin alphabet, such as Mohawk and Yoruba, and with non-Latin writing systems such as the Greek and Cyrillic alphabets and the Bopomofo or Zhuyin Fuhao semi-syllabary. It has no single meaning, but can indicate pitch, stress, or other features. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available. For less-used and compound diacritics, a combining character facility is available. A free-standing version of the symbol, commonly called a backtick, also exists and has acquired other uses. Uses Pitch The grave accent first appeared in the polytonic orthography of Ancient Greek to mark a lower pitch than the high pitch of the acute accent. In modern practice, it ...

Underscore
An underscore, ; also called an underline, low line, or low dash; is a line drawn under a segment of text. In proofreading, underscoring is a convention that says "set this text in italic type", traditionally used on Manuscript (publishing), manuscript or Manuscript#Modern variations, typescript as an List of proofreader's marks, instruction to the printer. Its use to add emphasis in modern documents is a deprecated practice. The underscore character, , originally appeared on the typewriter and was primarily used to emphasise words as in #Manuscripts, the proofreader's convention. To produce an underscored word, the word was typed, the typewriter carriage was moved back to the beginning of the word, and the word was overstrike, overtyped with the underscore character. In modern usage, underscoring is achieved by Markup language, markup or with combining characters. The original free-standing underscore character continues in use to create visual spacing within a sequence of char ...

Circumflex
The circumflex () is a diacritic in the Latin and Greek scripts that is also used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from la, circumflexus "bent around"a translation of the el, περισπωμένη (). The circumflex in the Latin script is chevron-shaped (), while the Greek circumflex may be displayed either like a tilde () or like an inverted breve (). For the most commonly encountered uses of the accent in the Latin alphabet, precomposed characters are available. In English, the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language (for example, ''crème brûlée''). In mathematics and statistics, the circumflex diacritic is sometimes used to denote a function and is called a ''hat operator''. A free-standing version of the circumflex symbol, , has become known as ''caret'' and has acquired special uses, particularly in computing ...

Backslash
The backslash is a typographical mark used mainly in computing and mathematics. It is the mirror image of the common slash . It is a relatively recent mark, first documented in the 1930s. History , efforts to identify either the origin of this character or its purpose before the 1960s have not been successful. The earliest known reference found to date is a 1937 maintenance manual from the Teletype Corporation with a photograph showing the keyboard of its Kleinschmidt keyboard perforator WPE-3 using the Wheatstone system. The symbol was called the "diagonal key", and given a (non-standard) Morse code of . (This is the code for the slash symbol, entered backwards.) In June 1960, IBM published an "Extended character set standard" that includes the symbol at 0x19. Referencing Computer Standards Collection, Archives Center, National Museum of American History, Smithsonian Institution, box 1. In September 1961, Bob Bemer (IBM) proposed to the X3.2 standards committee that ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Question Mark
The question mark (also known as interrogation point, query, or eroteme in journalism) is a punctuation mark that indicates an interrogative clause or phrase in many languages. History In the fifth century, Syriac Bible manuscripts used question markers, according to a 2011 theory by manuscript specialist Chip Coakley: he believes the ''zagwa elaya'' ("upper pair"), a vertical double dot over a word at the start of a sentence, indicates that the sentence is a question. From around 783, in ''Godescalc Evangelistary'', a mark described as "a lightning flash, striking from right to left" is attested. This mark is later called a . According to some paleographers, it may have indicated intonation, perhaps associated with early musical notation like neumes. Another theory, is that the "lightning flash" was originally a tilde or titlo, as in , one of many wavy or more or less slanted marks used in medieval texts for denoting things such as abbreviations, which would later become ...

Greater-than Sign
The greater-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the right, , has been found in documents dated as far back as the 1560s. In mathematical writing, the greater-than sign is typically placed between two values being compared and signifies that the first number is greater than the second number. Examples of typical usage include ''1.5 > 1'' and ''1 > −2''. The less-than sign and greater-than sign always "point" to the smaller number. Since the development of computer programming languages, the greater-than sign and the less-than sign have been repurposed for a range of uses and operations. History The earliest known use of the symbols and is found in (''The Analytical Arts Applied to Solving Algebraic Equations'') by Thomas Harriot, published posthumously in 1631. The text states: " a > b a b (The sign of majority a > ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Equal Sign
The equals sign (British English, Unicode) or equal sign (American English), also known as the equality sign, is the mathematical symbol , which is used to indicate equality in some well-defined sense. In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the same value. In Unicode and ASCII, it has the code point U+003D. It was invented in 1557 by Robert Recorde. History The etymology of the word "equal" is from the Latin word "''æqualis",'' as meaning "uniform", "identical", or "equal", from ''aequus'' ("level", "even", or "just"). The symbol, now universally accepted in mathematics for equality, was first recorded by Welsh mathematician Robert Recorde in ''The Whetstone of Witte'' (1557). The original form of the symbol was much wider than the present form. In his book Recorde explains his design of the "Gemowe lines" (meaning ''twin'' lines, from the Latin '' gemellus'')See also g ...
