Code Page 867
Code page 867 (CCSID 867) is a Hebrew 8-bit code page defined by IBM in 1998. It is based on Code page 862 but replaces several characters not used in Hebrew with nonprinting characters for bidirectional text support, a euro sign and a shekel sign. The code page ID is conflictive with a NEC code page for the Kamenický encoding The Kamenický encoding (), named for the brothers Jiří and Marian Kamenický, was a code page for personal computers running DOS, very popular in Czechoslovakia (since 1993, the Czech Republic and Slovakia) around 1985–1995.

Extended ASCII
Extended ASCII is a repertoire of character encodings that include (most of) the original 96 ASCII character set, plus up to 128 additional characters. There is no formal definition of "extended ASCII", and even use of the term is sometimes criticized, because it can be mistakenly interpreted to mean that the American National Standards Institute (ANSI) had updated its standard to include more characters, or that the term identifies a single unambiguous encoding, neither of which is the case. The ISO standard ISO 8859 was the first international standard to formalise a (limited) expansion of the ASCII character set: of the many language variants it encoded, ISO 8859-1 ("ISO Latin 1")which supports most Western European languages is best known in the West. There are many other extended ASCII encodings (more than 220 DOS and Windows codepages). EBCDIC ("the other" major character code) likewise developed many extended variants (more than 186 EBCDIC codepages) over the decades. All ...

Miscellaneous Technical (Unicode Block)
Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF. It contains various common symbols which are related to and used in the various technical, programming language, and academic professions. For example: * Symbol ⌂ (HTML hexadecimal code is ⌂) represents a house or a home. * Symbol ⌘ (⌘) is a "place of interest" sign. It may be used to represent the ''Command key'' on a Apple keyboard, Mac keyboard. * Symbol ⌚ (⌚) is a watch (or clock). * Symbol ⏏ (⏏) is the "Eject" button symbol found on electronic equipment. * Symbol ⏚ (⏚) is the "Electrical ground, Earth Ground" symbol found on electrical or electronic manual, tag and equipment. It also includes most of the uncommon symbols used by the APL syntax and symbols, APL programming language. Miscellaneous Technical (2300–23FF) in Unicode In Unicode, ''Miscellaneous Technical'' symbols placed in the hexadecimal range 0x2300–0x23FF, (decimal ...

Code Page 862
Code page 862 ( CCSID 862) (also known as CP 862, IBM 00862, OEM 862 (Hebrew), MS-DOS Hebrew) is a code page used under DOS in Israel for Hebrew. Like ISO 8859-8, it encodes only letters, not vowel-points or cantillation marks. As DOS had no inherent bidirectionality support, Hebrew text encoded using code page 862 was usually stored in visual order; nevertheless, a few DOS applications, notably a word processor named EinsteinWriter, stored Hebrew in logical order. Code page 862 was replaced by Windows-1255 in Windows 3.x and 9x systems, and later by Unicode in Windows NT onwards. It is now obsolete. Character set The following table shows code page 862. It has the Hebrew letters in code positions 128–154 (80–9Ahex), but otherwise it is identical to code page 437. Each character is shown with its equivalent Unicode code point. Only the second half of the table (code points 128–255) is shown, the first half (code points 0–127) being the same as code page 437. Referen ...

Non-breaking Space
In word processing and digital typesetting, a non-breaking space (), also called NBSP, required space, hard space, or fixed space (in most typefaces, it is not of fixed width), is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive whitespace characters from collapsing into a single space. Non-breaking space characters with other widths also exist. Uses Despite having layout and uses similar to those of whitespace, it differs in contextual behavior. Non-breaking behavior Text-processing software typically assumes that an automatic line break may be inserted anywhere a space character occurs; a non-breaking space prevents this from happening (provided the software recognizes the character). For example, if the text "100 km" will not quite fit at the end of a line, the software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inequality (mathematics)
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. The main types of inequality are less than and greater than (denoted by and , respectively the less-than sign, less-than and greater-than sign, greater-than signs). Notation There are several different notations used to represent different kinds of inequalities: * The notation ''a'' ''b'' means that ''a'' is greater than ''b''. In either case, ''a'' is not equal to ''b''. These relations are known as strict inequalities, meaning that ''a'' is strictly less than or strictly greater than ''b''. Equality is excluded. In contrast to strict inequalities, there are two types of inequality relations that are not strict: * The notation ''a'' ≤ ''b'' or ''a'' ⩽ ''b'' or ''a'' ≦ ''b'' means that ''a'' is less than or equal to ''b'' (or, equivalently, at most ''b'', or no ...

Identity (mathematics)
In mathematics, an identity is an equality (mathematics), equality relating one mathematical expression ''A'' to another mathematical expression ''B'', such that ''A'' and ''B'' (which might contain some variable (mathematics), variables) produce the same value for all values of the variables within a certain domain of discourse. In other words, ''A'' = ''B'' is an identity if ''A'' and ''B'' define the same function (mathematics), functions, and an identity is an equality between functions that are differently defined. For example, (a+b)^2 = a^2 + 2ab + b^2 and \cos^2\theta + \sin^2\theta =1 are identities. Identities are sometimes indicated by the triple bar symbol instead of , the equals sign. Formally, an identity is a universally quantified equality. Common identities Algebraic identities Certain identities, such as a+0=a and a+(-a)=0, form the basis of algebra, while other identities, such as (a+b)^2 = a^2 + 2ab +b^2 and a^2 - b^2 = (a+b)(a-b), ...

Sigma
Sigma ( ; uppercase Σ, lowercase σ, lowercase in word-final position ς; ) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator (mathematics), operator for summation. When used at the end of a Letter case, letter-case word (one that does not use all caps), the final form (ς) is used. In ' (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end. The Latin alphabet, Latin letter S derives from sigma while the Cyrillic script, Cyrillic letter Es (Cyrillic), Es derives from a #Lunate sigma, lunate form of this letter. History The shape (Σς) and alphabetic position of sigma is derived from the Phoenician alphabet, Phoenician letter (Shin (letter), ''shin''). Sigma's original name may have been ''san'', but due to the complicated early history of the Greek Archaic Greek alphabets, epich ...

Pi (letter)
Pi (; Ancient Greek or , uppercase Π, lowercase π, cursive ϖ; ) is the sixteenth letter of the Greek alphabet, representing the voiceless bilabial plosive . In the system of Greek numerals it has a value of 80. It was derived from the Phoenician alphabet, Phoenician letter Pe (Semitic letter), Pe (). Letters that arose from pi include Latin alphabet, Latin P, Cyrillic script, Cyrillic Pe (Cyrillic), Pe (П, п), Coptic alphabet, Coptic pi (Ⲡ, ⲡ), and Gothic alphabet, Gothic pairthra (𐍀). Uppercase Pi The uppercase letter Π is used as a symbol for: * In textual criticism, ''Codex Petropolitanus (New Testament), Codex Petropolitanus'', a 9th-century uncial codex of the Gospels, now located in St. Petersburg, Russia. * In legal shorthand, it represents a plaintiff. * In Mathematical finance, it represents a portfolio. Greek letters used in mathematics, science, and engineering, In science and engineering: * The product (mathematics), product operator in mathematics, i ...

Fraction (mathematics)
A fraction (from , "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A ''common'', ''vulgar'', or ''simple'' fraction (examples: and ) consists of an integer numerator, displayed above a line (or before a slash like ), and a division by zero, non-zero integer denominator, displayed below (or after) that line. If these integers are positive, then the numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. For example, in the fraction , the numerator 3 indicates that the fraction represents 3 equal parts, and the denominator 4 indicates that 4 parts make up a whole. The picture to the right illustrates of a cake. Fractions can be used to represent ratios and division (mathematics), division. Thus the fraction can be used to ...

Kamenický Encoding
The Kamenický encoding (), named for the brothers Jiří and Marian Kamenický, was a code page for personal computers running DOS, very popular in Czechoslovakia (since 1993, the Czech Republic and Slovakia) around 1985–1995. Another name for this encoding is KEYBCS2, the name of the terminate-and-stay-resident utility which implemented the matching keyboard driver. It was also named KAMENICKY. It was based on the code page 437 encoding (with accented characters for Western-European languages) where most of the characters from code points 128 to 173 were replaced by Czech and Slovak characters chosen so that the glyphs of the replacement characters resembled those of the original as closely as possible, e. g. č in the place of ç. This ensured that text in the Kamenický encoding was (barely) readable even on older or cheap computers with the original fonts (which were often in videocard ROM, making modification difficult if not impossible). A supplemental feature was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bidirectional Text
A bidirectional text contains two text directionalities, right-to-left (RTL) and left-to-right (LTR). It generally involves text containing different types of alphabets, but may also refer to boustrophedon, which is changing text direction in each row. An example is the RTL Hebrew name Sarah: , spelled sin (ש) on the right, resh (ר) in the middle, and heh (ה) on the left. Many computer programs failed to display this correctly, because they were designed to display text in one direction only. Some so-called right-to-left scripts such as the Persian script and Arabic are mostly, but not exclusively, right-to-left—mathematical expressions, numeric dates and numbers bearing units are embedded from left to right. That also happens if text from a left-to-right language such as English is embedded in them; or vice versa, if Arabic is embedded in a left-to-right script such as English. Bidirectional script support Bidirectional script support is the capability of a comput ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shekel Sign
The shekel sign ⟨₪⟩ is a currency sign used for the shekel, the currency of Israel. Israeli new shekel (1986–present) The Israeli new shekel (, ), also known by the acronym NIS ( ), was announced officially on 22 September 1985, when the first new shekel banknotes and coins were introduced. It is constructed by combining the two Hebrew letters that constitute the acronym (the first letter of each of the two words, Hebrew being written from right to left): ⟨ ש⟩ and ⟨ ח⟩. Sometimes the ⟨₪⟩ symbol (Unicode 20AA) is used following the number, other times the acronym . The shekel sign, like the dollar sign ⟨$⟩, is usually placed left of the number (i.e. "₪12,000" and not "12,000₪"), but since Hebrew is written from right to left, this means that the symbol is actually written after the number. It is either not separated from the preceding number, or is separated only by a thin space. According to the Academy of the Hebrew Language recommenda ...
