In most current use cases, the letters A–F or a–f represent the values 10–15, while the numerals 0–9 are used to represent their decimal values.. There is no universal convention to use lowercase or uppercase, so each is prevalent or preferred in particular environments by community standards or convention; even mixed case is used.
Each language is assigned a two-letter (set 1) and three-letter lowercase abbreviation (sets 2–5). [2] Part 1 of the standard, ISO 639-1 defines the two-letter codes, and Part 3 (2007), ISO 639-3, defines the three-letter codes, aiming to cover all known natural languages, largely superseding the ISO 639-2 three-letter code standard.
This is a list of future area codes in the North American Numbering Plan (NANP) that are in the planning stages for relief of central office code exhaustion in the given numbering plan areas (NPAs). The dates are subject to change during implementation as published in the official NANP Administrator Planning Letters.
First-order means that only the first derivative of y appears in the equation, and higher derivatives are absent. Without loss of generality to higher-order systems, we restrict ourselves to first-order differential equations, because a higher-order ODE can be converted into a larger system of first-order equations by introducing extra variables.
Massachusetts is divided into five distinct numbering plan areas (NPAs), which are served by nine area codes in the North American Numbering Plan (NANP), [1] organized as four overlay complexes and a single-area code NPA. Eastern Massachusetts has area codes 339, 351, 508, 617, 774, 781, 857, and 978. [2] Western Massachusetts has area code 413 ...
With Arkansas being relatively sparsely populated, this arrangement worked well until 1997, when the phone numbers in area code 501 were in danger of being used up. Area code 870 was created in April 1997 to serve the most rural parts of the state (originally specifically not Little Rock metro , Fort Smith or Northwest Arkansas ).
The 219 area code covers the northwest part of the state, including the cities of Gary, Hammond, Merrillville, Valparaiso and Michigan City. The 574 area code covers north-central Indiana, and includes the cities of South Bend, North Judson and Warsaw. The 260 area code covers the northeast section of Indiana, including Fort Wayne and Angola.
Area codes 210 and 726 are telephone area codes in the North American Numbering Plan (NANP) for the San Antonio area in the U.S. state of Texas. Area code 210 was created in an area code split from number plan area 512 in 1992. After only a few years, the threat of number exhaustion forced a reduction of the size of the numbering plan area to ...
