One half is the irreducible fraction resulting from dividing one by two (2) or the fraction resulting from dividing any number by its double. Multiplication by one half is equivalent to division by two, or "halving"; conversely, division by one half is equivalent to multiplication by two, or "doubling". One half often appears in mathematical equations, recipes, measurements, etc. Half can also be said to be one part of something divided into two equal parts.
The Tamil script is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore, Indonesia and elsewhere to write the Tamil language. Certain minority languages such as Saurashtra, Badaga, Irula and Paniya are also written in the Tamil script.
Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. These characters allow any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
In Unicode, a Private Use Area (PUA) is a range of code points that, by definition, will not be assigned characters by the Unicode Consortium. Three private use areas are defined: one in the Basic Multilingual Plane, and one each in, and nearly covering, planes 15 and 16. The code points in these areas cannot be considered as standardized characters in Unicode itself. They are intentionally left undefined so that third parties may define their own characters without conflicting with Unicode Consortium assignments. Under the Unicode Stability Policy, the Private Use Areas will remain allocated for that purpose in all future Unicode versions.
Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters. They consist primarily of vulgar fractions and Roman numerals. In addition to the characters in the Number Forms block, three fractions were inherited from ISO-8859-1, which was incorporated whole as the Latin-1 supplement block.
This article is about the number words of the Tamil language, as well as the dedicated symbols for them used in the Tamil script.
In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but is nonetheless available for use as part of a text.
The Unicode Consortium (UC) and the International Organisation for Standardisation (ISO) collaborate on the Universal Character Set (UCS). The UCS is an international standard to map characters used in natural language, mathematics, music, and other domains to machine-readable values. By creating this mapping, the UCS enables computer software vendors to interoperate and transmit UCS-encoded text strings from one to another. Because it is a universal map, it can be used to represent multiple languages at the same time. This avoids the confusion of using multiple legacy character encodings, which can result in the same sequence of codes having multiple meanings and thus be improperly decoded if the wrong one is chosen.
In Unicode and the UCS, a compatibility character is a character that is encoded solely to maintain round-trip convertibility with other, often older, standards. As the Unicode Glossary says:
A character that would not have been encoded except for compatibility and round-trip convertibility with other standards
A numeral is a character that denotes a number. Decimal is used widely in various writing systems throughout the world, however the graphemes representing the decimal digits differ widely, therefore Unicode includes 22 different sets of graphemes for the decimal digits, and also various decimal points, thousands separators, negative signs, etc. Unicode also includes several non-Decimal numerals such as Aegean numerals, Roman numerals, counting rod numerals, Cuneiform numerals and ancient Greek numerals. There is also a large number of typographical variations of the Western Arabic numerals provided for specialized mathematical use and for compatibility with earlier character sets, such as ² or ②, and composite characters such as ½.
In the Unicode standard, a plane is a continuous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version 13.0, seven of the planes have assigned code points (characters), and five are named.
The Latin-1 Supplement is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). Controls C1 (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.
The Unicode Standard assigns various properties to each Unicode character and code point.
The rupee sign “₨” is a currency sign used to represent the monetary unit of account in Pakistan, Sri Lanka, Nepal, Mauritius, Seychelles, and formerly in India. It resembles, and is often written as, the Latin character sequence "Rs", of which it is an orthographic ligature.
Symbols and Pictographs Extended-A is a Unicode block containing emoji characters. It extends the set of symbols included in the Supplemental Symbols and Pictographs block.
Small Kana Extension is a Unicode block containing additional small variants for the Hiragana and Katakana syllabaries, in addition to those in the Hiragana, Katakana and Katakana Phonetic Extensions blocks.
A number of Greek letters, variants, digits, and other symbols are supported by the Unicode character encoding standard.
Symbols for Legacy Computing is a Unicode block containing graphic characters that were used for various home computers from the 1970s and 1980s and in Teletext broadcasting standards. It includes characters from the Amstrad CPC, MSX, Mattel Aquarius, RISC OS, MouseText, Atari ST, TRS-80 Color Computer, Oric, Texas Instruments TI-99/4A, TRS-80, Minitel, Teletext, ATASCII, PETSCII, ZX80, and ZX81 character sets, as well as semigraphics characters.
KS X 1002 is a South Korean character set standard that is established in order to supplement KS X 1001. It consists of a total of 7,649 characters.
