In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications.
The decimal numeral system is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as decimal notation.
The duodecimal system, also known as base twelve or dozenal, is a positional numeral system using twelve as its base. In duodecimal, the number twelve is denoted "10", meaning 1 twelve and 0 units; in the decimal system, this number is instead written as "12" meaning 1 ten and 2 units, and the string "10" means ten. In duodecimal, "100" means twelve squared, "1000" means twelve cubed, and "0.1" means a twelfth.
In computing, floating-point arithmetic (FP) is arithmetic that represents subsets of real numbers using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. Numbers of this form are called floating-point numbers. For example, 12.345 is a floating-point number in base ten with five digits of precision:
In mathematics and computing, the hexadecimal numeral system is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" to represent values from ten to fifteen.
Hawaiian is a Polynesian language and critically endangered language of the Austronesian language family that takes its name from Hawaiʻi, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840.
Octal is a numeral system with eight as the base.
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form, since to do so would require writing out an inconveniently long string of digits. It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators, it is usually known as "SCI" display mode.
A decimal separator is a symbol used to separate the integer part from the fractional part of a number written in decimal form. Different countries officially designate different symbols for use as the separator. The choice of symbol also affects the choice of symbol for the thousands separator used in digit grouping.
A vigesimal or base-20 (base-score) numeral system is based on twenty. Vigesimal is derived from the Latin adjective vicesimus, meaning 'twentieth'.
The Tibetan script is a segmental writing system (abugida) of Indic origin used to write certain Tibetic languages, including Tibetan, Dzongkha, Sikkimese, Ladakhi, Jirel and Balti. It has also been used for some non-Tibetic languages in close cultural contact with Tibet, such as Thakali and Old Turkic. The printed form is called uchen script while the hand-written cursive form used in everyday writing is called umê script. This writing system is used across the Himalayas and Tibet.
Count Nogi Maresuke, also known as Kiten, Count Nogi, was a Japanese general in the Imperial Japanese Army and a governor-general of Taiwan. He was one of the commanders during the 1894 capture of Port Arthur from China and a prominent figure in the Russo-Japanese War of 1904–05, as commander of the forces which captured Port Arthur from the Russians.
When used as a diacritic mark, the term dot refers to the glyphs "combining dot above", and "combining dot below" which may be combined with some letters of the extended Latin alphabets in use in a variety of languages. Similar marks are used with other scripts.
Positional notation usually denotes the extension to any base of the Hindu–Arabic numeral system. More generally, a positional system is a numeral system in which the contribution of a digit to the value of a number is the value of the digit multiplied by a factor determined by the position of the digit. In early numeral systems, such as Roman numerals, a digit has only one value: I means one, X means ten and C a hundred. In modern positional systems, such as the decimal system, the position of the digit means that its value must be multiplied by some value: in 555, the three identical symbols represent five hundreds, five tens, and five units, respectively, due to their different positions in the digit string.
Geʽez is a script used as an abugida (alphasyllabary) for several Afro-Asiatic and Nilo-Saharan languages of Ethiopia and Eritrea. It originated as an abjad and was first used to write the Geʽez language, now the liturgical language of the Ethiopian Orthodox Tewahedo Church, the Eritrean Orthodox Tewahedo Church, the Eritrean Catholic Church, the Ethiopian Catholic Church, and Haymanot Judaism of the Beta Israel Jewish community in Ethiopia. In the languages Amharic and Tigrinya, the script is often called fidäl (ፊደል), meaning "script" or "letter". Under the Unicode Standard and ISO 15924, it is defined as Ethiopic text.
Dagaare is the language of the Dagaaba people of Ghana, Burkina Faso, and Ivory Coast. It has been described as a dialect continuum that also includes Waale and Birifor. Dagaare language varies in dialect stemming from other family languages including: Dagbane, Waale, Mabia, Gurene, Mampruli, Kusaal, Buli, Niger-Congo, and many other sub languages resulting in around 1.3 million Dagaare speakers. Throughout the regions of native Dagaare speakers the dialect comes from Northern, Central, Western, and Southern areas referring to the language differently. Burkina Faso refers to Dagaare as Dagara and Birifor to natives in the Republic of Côte d'Ivoire. The native tongue is still universally known as Dagaare. Amongst the different dialects, the standard for Dagaare is derived from the Central region's dialect. Southern Dagaare also stems from the Dagaare language and is known to be commonly spoken in Wa and Kaleo.
DNA-directed RNA polymerases I and III subunit RPAC1 is a protein that in humans is encoded by the POLR1C gene.
The East Strickland or Strickland River languages are a family of Papuan languages.
Kaṭapayādi system of numerical notation is an ancient Indian alphasyllabic numeral system to depict letters to numerals for easy remembrance of numbers as words or verses. Assigning more than one letter to one numeral and nullifying certain other letters as valueless, this system provides the flexibility in forming meaningful words out of numbers which can be easily remembered.
The NOGI Awards is an award presented annually by the Academy of Underwater Arts and Sciences (AUAS) to diving luminaries and is "considered the Oscar of the ocean world." Selection of recipients is based on their record of accomplishments and excellence in the diving world. NOGI awards are given out to world-class standouts of the diving community who have distinguished themselves and made a global impact on diving in one or more of four general categories: Science, Arts, Sports/Education, and Environment. A fifth NOGI is given for Distinguished Service.
