Indian numbering system

The Indian numbering system is used in India as well as in Bangladesh, Nepal, Pakistan, and Sri Lanka. It is based on the Vedic numbering system in which numbers over 9,999 are written in two-digit groups (or a mix of two- and three-digit groups) rather than the three-digit groups used in most other parts of the world. In Pakistan, this system is used in Urdu and other regional language media, but not in English-language media.

The terms lakh (100,000 or 1,00,000 in the Indian system) and crore (10,000,000 or 1,00,00,000 in the Indian system) are used in Indian English to express large numbers. For example, in India 150,000 rupees becomes 1.5 lakh rupees, written as ₹1,50,000 or INR 1,50,000, while 30,000,000 (thirty million) rupees becomes 3 crore rupees, written as ₹3,00,00,000 with commas at the thousand, lakh, and crore levels, and 1,000,000,000 (one billion) rupees (one hundred crore rupees) is written ₹1,00,00,00,000.

Use of separators

The Indian numbering system uses separators differently from the international norm; in such numbers of at least one lakh (one hundred thousand), a comma divides every two rather than every three digits, thus:

Arabs in India

A small but recognizable people with Arab origins have over time settled in the India.Many who arrived in Gujarat were later recruited to the army. Most Gujarati Arabs were traders, and business men who sold or traded silk, diamonds and other valuables resulting in wealthy business men. The city of Surat and villages within the city are notorious for Arab settlements. Variav and Randev are the few villages that Arabs started their lives in. In Eastern Uttar Pradesh, Iraqis arrived in 15th and 16th century from Sindh, Pakistan. These people claim ancestry from Arab tribe of Bani Tamim.In Hyderabad, Chaush are Arab community of Hadhrami descent whose ancestors were recruited as soldier by Nizam of Hyderabad. In Kerala, Syed Thangals of Hadhrami descent settled around 17th century as missionaries to propagate Islam. There are also Shia Sayyids in Northern region of country who claim descent from Wasit, Iraq like Zaidis. Sunni Sayyid of the country also claim Arab descent from Sufi missionaries but it is hard to say that every Sufi really belonged to Arab. Most of the Sufis migrated from Persia. Sunni Sayyid also include converts from higher Hindu castes like Brahmin and Kshatriya. Sunni Sheikhs also claim Arab descent from Sufis or migrants but it remains hoax. They don't know their tribe but trace lineage from Umar, Abu Bakr and Uthman, the Rashidun Caliphate. Many of present Sheikhs converted from Hindu castes such as Kayasth and Rajput.

Arab (etymology)

The proper name Arab or Arabian (and cognates in other languages) has been used to translate several different but similar sounding words in ancient and classical texts which do not necessarily have the same meaning or origin. The etymology of the term is of course closely linked to that of the place name Arabia. Gustave E. von Grunebaum, in his book Classical Islam said that an approximate translation is passerby or nomad.

Semitic etymology

The root of the word has many meanings in Semitic languages including west/sunset, desert, nomad, merchant, raven and comprehensible with all of these having varying degrees of relevance to the emergence of the name. It is also possible that some forms were metathetical from عبر ʿ-B-R "moving around" (Arabic عرب ʿ-B-R "traverse"), and hence, it is alleged, "nomadic."

The plurality of meanings results partly from the assimilation of the proto-Semitic غ ghayin with ع ʿayin in some languages. In Hebrew the word ערב ʿarav thus has the same triconsonantal root as the root meaning "west" (מערב maʿarav) "setting sun" or "evening" (מעריב maʿariv, ערב ʿerev). The direct Arabic cognate of this is غرب ġarb ("west", etc.) rather than عرب ʿarab ; however, in Ugaritic and Sayhadic, languages which normally preserve proto-Semitic ghayin, this root is found with ʿayin adding to the confusion.The first recorded use of the word is in Hebrew, Exodus 12:38, and its meaning there is a "mixture" of people who accompanied the Israelites as they left Egypt.

Index

An index is an indirect shortcut derived from and pointing into a greater volume of values, data, information or knowledge. Index may refer to:

Business

Publishing

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Index (typography)

The symbol ☞ is a punctuation mark, called an index, manicule (from the Latin root manus for "hand" and manicula for "little hand") or fist. Other names for the symbol include printer's fist, bishop's fist, digit, mutton-fist, hand, hand director, pointer, and pointing hand.

History

The symbol originates in scribal tradition of the medieval and Renaissance period, appearing in the margin of manuscripts to mark corrections or notes.

Manicules are first known to appear in the 12th century in handwritten manuscripts in Spain, and became common in the 14th and 15th centuries in Italy with some very elaborate with shading and artful cuffs. Some were playful and elaborate, but others were as simple as "two squiggly strokes suggesting the barest sketch of a pointing hand" and thus quick to draw.

After the popularization of the printing press starting in the 1450s, the handwritten version continued in handwritten form as a means to annotate printed documents. Early printers using a type representing the manicule included Mathias Huss and Johannes Schabeler in Lyons in their 1484 edition of Paulus Florentinus' Breviarum totius juris canonici.
