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 ...

Internet Assigned Numbers Authority
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, Autonomous system (Internet), autonomous system number allocation, DNS root zone, root zone management in the Domain Name System (DNS), Internet media type, media types, and other Internet Protocol–related symbols and Internet numbers. Currently it is a function of ICANN, a nonprofit private American corporation established in 1998 primarily for this purpose under a United States Department of Commerce contract. ICANN managed IANA directly from 1998 through 2016, when it was transferred to Public Technical Identifiers (PTI), an affiliate of ICANN that operates IANA today. Before it, IANA was administered principally by Jon Postel at the Information Sciences Institute (ISI) of the University of Southern California (USC) situated at Marina Del Rey (Los Angeles), under a contract USC/ISI had with the United States Department of Defense. In addition, five regional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miscellaneous Technical (Unicode Block)
Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF.

ISO 646
ISO/IEC 646 ''Information technology — ISO 7-bit coded character set for information interchange'', is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard in the field of character encoding. It is equivalent to the Ecma International, ECMA standard ECMA-6 and developed in cooperation with ASCII at least since 1964. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. The first edition of ISO/IEC 646 was published in 1973, and the most recent, third, edition in 1991. ISO/IEC 646 specifies a 7-bit character code from which several national standards are derived. It allocates a set of 82 unique graphic characters to 7-bit code points, known as the ''invariant'' (INV) or ''basic character set'', including letters of the ISO basic Latin alphabet, Numerical digit, digits, and some common English language, English pun ...

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 ...

Spanish Peseta
The peseta (, ) was the currency of Spain between 1868 and 2002. Along with the French franc, it was also a de facto currency, ''de facto'' currency used in Andorra (which had no national currency with legal tender). Etymology The name of the currency derives from ''peceta'', a Catalan Language, Catalan word meaning ''little piece,'' from of the Catalan word ''peça'' (lit. ''piece'', "coin"). Its etymology has wrongly been attributed to the Spanish ''peso''. The word ''peseta'' has been known as early as 1737 to colloquially refer to the coin worth 2 ''reales provincial'' or of a peso. Coins denominated in "pesetas" were briefly issued in 1808 in Barcelona under French occupation; see Catalan peseta. Symbol Traditionally, there was never a single symbol or special character for the Spanish peseta. Common abbreviations were "Pta" (plural: "Pts), "Pt", and "Ptas". A common way of representing amounts of pesetas in print was using superior letters: "Pta" and "Pts". Common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCSID
A CCSID (coded character set identifier) is a 16-bit number that represents a particular encoding of a specific code page. For example, Unicode is a code page that has several character encoding schemes (referred to as "transformation formats")—including UTF-8, UTF-16 and UTF-32—but which may or may not actually be accompanied by a CCSID number to indicate that this encoding is being used. Difference between a code page and a CCSID The terms code page and CCSID are often used interchangeably, even though they are not synonymous. A code page may be only part of what makes up a CCSID. The following definitions from IBM help to illustrate this point: * A glyph is the actual physical pattern of pixels or ink that shows up on a display or printout. * A character is a concept that covers all glyphs associated with a certain symbol. For instance, "F", "F", "''F''", "", "", and "" are all different glyphs, but use the same character. The various modifiers (bold, italic, underline, co ...

Code Page 437
Code page 437 ( CCSID 437) is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or MS-DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII" (one of many mutually incompatible ASCII extensions). This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set. Many file formats developed at the time of the IBM PC are based on code page 437 as well. Display adapters The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( ...
