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 on subsets of real numbers formed by a signed sequence of a fixed number of digits in some base, called a significand, scaled by an integer exponent of that base. Numbers of this form are called floating-point numbers.
Hexadecimal 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 Hawaiʻi. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840.
A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.
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 that separates 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, or abugida, derived from Brahmic scripts and Gupta script, and used to write certain Tibetic languages, including Tibetan, Dzongkha, Sikkimese, Ladakhi, Jirel and Balti. It was originally developed c. 620 by Tibetan minister Thonmi Sambhota for King Songtsen Gampo.
Positional notation, also known as place-value notation, positional numeral system, or simply place value, 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.
The Biu–Mandara or Central Chadic languages of the Afro-Asiatic family are spoken in Nigeria, Chad and Cameroon.
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.
Demsa is a Local Government Area of Adamawa State, Nigeria with headquarters located in Demsa. Demsa lies on the Benue River.
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 Bamum scripts are an evolutionary series of six scripts created for the Bamum language by Ibrahim Njoya, King of Bamum. They are notable for evolving from a pictographic system to a semi-syllabary in the space of fourteen years, from 1896 to 1910. Bamum type was cast in 1918, but the script fell into disuse around 1931. A project began around 2007 to revive the Bamum script.
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.
