  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    This has been followed by subsequent spreadsheets, such as Microsoft Excel, and complemented by specialized VLOOKUP and HLOOKUP functions to simplify lookup in a vertical or horizontal table. In Microsoft Excel the XLOOKUP function has been rolled out starting 28 August 2019.

  3. Reference data - Wikipedia

    en.wikipedia.org/wiki/Reference_data

    For most organisations, most or all reference data is defined and managed within that organisation. Some reference data, however, may be externally defined and managed, for example by standards organizations. [5] An example of externally-defined reference data is the set of country codes as defined in ISO 3166-1. [6] [7]

  4. Range searching - Wikipedia

    en.wikipedia.org/wiki/Range_searching

    In the semigroup version, a commutative semigroup (S,+) is specified, each point is assigned a weight from S, and it is required to report the semigroup sum of the weights of the points that intersect the range. Dynamic range searching vs. static range searching: In the static setting the set S is known in advance. In dynamic setting objects ...

  5. Range table - Wikipedia

    en.wikipedia.org/wiki/Range_table

    A range table was a list of angles of elevation a particular artillery gun barrel needed to be set to, to strike a target at a particular distance with a projectile of a particular weight using a propellant cartridge of a particular weight.

  6. Range tree - Wikipedia

    en.wikipedia.org/wiki/Range_tree

    A 1-dimensional range tree on a set of n points is a binary search tree, which can be constructed in (⁡) time. Range trees in higher dimensions are constructed recursively by constructing a balanced binary search tree on the first coordinate of the points, and then, for each vertex v in this tree, constructing a (d−1)-dimensional range tree on the points contained in the subtree of v.

  7. Ballistic table - Wikipedia

    en.wikipedia.org/wiki/Ballistic_table

    Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

  8. Dynamic/Dialup Users List - Wikipedia

    en.wikipedia.org/wiki/Dynamic/Dialup_Users_List

    A Dial-up/Dynamic User List (DUL) [1] is a type of DNSBL which contains the IP addresses an ISP assigns to its customer on a temporary basis, often using DHCP or similar protocols. Dynamically assigned IP addresses are contrasted with static IP addresses which do not change once they have been allocated by the service provider.

  9. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    When an object is created, a pointer to this table, called the virtual table pointer, vpointer or VPTR, is added as a hidden member of this object. As such, the compiler must also generate "hidden" code in the constructors of each class to initialize a new object's virtual table pointer to the address of its class's virtual method table.
