Spigot algorithm. A spigot algorithm is an algorithm for computing the value of a transcendental number (such as π or e) that generates the digits of the number sequentially from left to right providing increasing precision as the algorithm proceeds. Spigot algorithms also aim to minimize the amount of intermediate storage required.
Spinneret. The spinnerets of an Australian garden orb weaver spider. A spinneret is a silk -spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. [1] Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented.
Bailey–Borwein–Plouffe formula. The Bailey–Borwein–Plouffe formula ( BBP formula) is a formula for π. It was discovered in 1995 by Simon Plouffe and is named after the authors of the article in which it was published, David H. Bailey, Peter Borwein, and Plouffe. [ 1] Before that, it had been published by Plouffe on his own site. [ 2]
They are called spigot algorithms because, like water dripping from a spigot, they produce single digits of π that are not reused after they are calculated. [ 140 ] [ 141 ] This is in contrast to infinite series or iterative algorithms, which retain and use all intermediate digits until the final result is produced.
Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture. [1] Silcock (and sillcock), same as "spigot", referring to a "cock" (as in stopcock and petcock) that penetrates a foundation sill. Bib (bibcock, and hose bib or hosebibb), usually a freeze-resistant version of a "spigot".
A spigot (or "tap" or "faucet") is a valve for controlling the release of a gas or liquid. Spigot may also refer to: AT-4 Spigot, NATO reporting name for 9K111 Fagot, a Russian anti-tank missile. Spigot, the male end of a pipe designed to be connected with a spigot and socket joint. Spigot, a keyed post in the center of some vacuum tube bases.
Japanese officers believed the 320 mm spigot mortar's most effective method of employment was to inflict psychological damage on the American troops instead of inflicting casualties. [ 8 ] [ 10 ] The 300 kg (660 lb) shells left craters 2.5 m (8 ft 2 in) deep and 4.5 m (15 ft) wide, but caused relatively few casualties due to minimal ...
The earliest spigot and socket cast iron pipes were jointed by filling the socket with a mixture of water, sand, iron filings and sal-ammoniac (ammonium chloride.) A gasket ring was pushed into the socket round the spigot to contain the mixture which was pounded into the socket with a caulking tool and then pointed off. This took several weeks ...
