Lighting and reflection calculations, as in the video game OpenArena, use the fast inverse square root code to compute angles of incidence and reflection.. Fast inverse square root, sometimes referred to as Fast InvSqrt() or by the hexadecimal constant 0x5F3759DF, is an algorithm that estimates , the reciprocal (or multiplicative inverse) of the square root of a 32-bit floating-point number in ...
The Latin word data is the plural of datum, "(thing) given," and the neuter past participle of dare, "to give". [6] The first English use of the word "data" is from the 1640s. The word "data" was first used to mean "transmissible and storable computer information" in 1946. The expression "data processing" was first used in 1954. [6]
The Sulba Sutras give methods for constructing a circle with approximately the same area as a given square, which imply several different approximations of the value of π. [130] [131] [a] In addition, they compute the square root of 2 to several decimal places, list Pythagorean triples, and give a statement of the Pythagorean theorem. [131]
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [6] [7] [8] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [9] the pattern of the position detection markers was determined by finding the least-used sequence of ...
The INPUT and INFILE statements were improved so they could read most data formats used by IBM mainframes. Generating reports was also added through the PUT and FILE statements. The ability to analyze general linear models was also added [29] as was the FORMAT procedure, which allowed developers to customize the appearance of data. [24]
Although Russian word stress is often unpredictable and can fall on different syllables in different forms of the same word, the diacritic accent is used only in dictionaries, children's books, resources for foreign-language learners, the defining entry (in bold) in articles on Russian Wikipedia, or on minimal pairs distinguished only by stress ...
A square is a parallelogram with one right angle and two adjacent equal sides. [1] A square is a quadrilateral with four equal sides and four right angles; that is, it is a quadrilateral that is both a rhombus and a rectangle [1] A square is a quadrilateral where the diagonals are equal, and are the perpendicular bisectors of each other.
The name "Topeka" is a Kansa-Osage word that means "place where we dig potatoes", [11] or "a good place to dig potatoes". [citation needed] As a placename, Topeka was first recorded in 1826 as the Kansa name for what is now called the Kansas River. Topeka's founders chose the name in 1855 because it "was novel, of Indian origin, and euphonious ...
