Pound per hour is a mass flow unit based on the international avoirdupois pound, which is used in both the British imperial and, being a former colony of Britain, the United States customary systems of measurement.
Simon Plouffe (born June 11, 1956) is a French Canadian mathematician who discovered the Bailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of the nth binary digit of π, in 1995. [1] [2] [3] His other 2022 formula allows extracting the nth digit of π in decimal. [4] He was born in Saint-Jovite, Quebec.
This does not compute the nth decimal digit of π (i.e., in base 10). [2] But another formula discovered by Plouffe in 2022 allows extracting the nth digit of π in decimal. [3] BBP and BBP-inspired algorithms have been used in projects such as PiHex [4] for calculating many digits of π using distributed computing. The existence of this ...
Bellard's formula is used to calculate the nth digit of π in base 16. Bellard's formula was discovered by Fabrice Bellard in 1997. It is about 43% faster than the Bailey–Borwein–Plouffe formula (discovered in 1995). [1] [2] It has been used in PiHex, the now-completed distributed computing project.
The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
Mathematics portal; 1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard, [1] long scale) is the natural number following ...
For example, 6 is highly composite because d(6)=4 and d(n)=1,2,2,3,2 for n=1,2,3,4,5 respectively. A related concept is that of a largely composite number , a positive integer that has at least as many divisors as all smaller positive integers.
Tetrakis(triphenylphosphine)palladium(0) (sometimes called quatrotriphenylphosphine palladium) is the chemical compound [Pd(P(C 6 H 5) 3) 4], often abbreviated Pd(PPh 3) 4, or rarely PdP 4. It is a bright yellow crystalline solid that becomes brown upon decomposition in air .
