This does not compute the nth decimal digit of π (i.e., in base 10). [3] But another formula discovered by Plouffe in 2022 allows extracting the nth digit of π in decimal. [4] BBP and BBP-inspired algorithms have been used in projects such as PiHex [5] 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.
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.
In other words, the n th digit of this number is 1 only if n is one of the numbers 1! = 1, 2! = 2, 3! = 6, 4! = 24, etc. Liouville showed that this number belongs to a class of transcendental numbers that can be more closely approximated by rational numbers than can any irrational algebraic number, and this class of numbers is called the ...
MEXICO CITY (Reuters) -The U.S. government deported drug lord Osiel Cardenas on Monday, transferring custody of the ex-Gulf Cartel chief known for hyper-violent tactics to Mexican authorities at ...

A recent study found that 6% of adults in the U.S. — or 1 in 8 — have taken the medication. While the decrease is an "encouraging reversal," the study says "obesity remains a considerable ...
Citigroup shares closed up 2.5%, Bank of America rose 1.4%, and Wells Fargo edged up 1.1% as the banking giants’ stocks gave back some of their earlier gains.
