Instead, it was Leonhard Euler in %%% September 1727 who first used the name pi for %%% the ratio of the periphery of a circle to its %%% radius ($ 2 \pi $ in modern notation); see %%% entry Euler:1727:TEP. He later used it for %%% the ratio of the periphery to the diameter, %%% and that convention was soon widely adopted. %%% %%% The constant pi was proved to be irrational %%% by Lambert in 1766, using a continued %%% fraction, and thus showing that the digits of %%% pi neither terminate, nor repeat in any %%% number base. %%% %%% In 1882, Lindemann proved that pi is also %%% transcendental, showing that the digits of an %%% integer polynomial of pi cannot repeat, and %%% thus, nonzero positive integral powers of pi %%% cannot have repeating decimals. %%% %%% Human interest in the problem of calculating %%% numerical values of pi has existed for more %%% than 1500 years, but it was only the advent %%% of electronic digital computers that made it %%% possible to advance beyond a few hundred %%% known digits. By mid-2010, the record for %%% correct decimal digits of pi stood at about 5 %%% * 10**12, and by late 2011, that had grown to %%% more than 10**13 (10 trillion) decimal %%% digits. See entries Bailey:2011:CPI and %%% Bailey:2013:PDU for tables of historical, %%% early computer, and modern computer records %%% for the digits of pi, and entry Yee:2013:IST %%% for the latest record. See entry %%% Shelburne:2012:ED for a reconstruction of the %%% first computer calculation of pi and e (about %%% 2000 decimal digits each), carried out on the %%% ENIAC on Labor Day (early September) weekend, %%% 1949. %%% %%% In 1997, a remarkable equation, the %%% now-famous BBP (Bailey, Borwein, and Plouffe) %%% formula was discovered. In (La)TeX markup %%% that produces a one-line typeset equation, it %%% can be stated like this: %%% %%% \pi = \sum_{k = 0}^\infty %%% \frac{1}{16^k} %%% \left ( %%% \frac{4}{8 k + 1} - %%% \frac{2}{8 k + 4} - %%% \frac{1}{8 k + 5} - %%% \frac{1}{4 k + 6} %%% \right ) %%% %%% The BBP discoverers showed that their formula %%% has the astonishing property that it can be %%% used to generate digits of pi in any base %%% that is a power of 2, STARTING from the n-th %%% digit, and WITHOUT knowing all previous %%% digits 1, 2, ..., n - 1. %%% %%% It has since been proved that no such formula %%% exists for pi in base 10, and that similar %%% formulas can be exhibited for other %%% constants, such as \pi^2, \zeta(2), \zeta(3), %%% Catalan's constant, \log(k) (k in [2, 22]), %%% and many arctangents. %%% %%% By contrast, it is conjectured that no such %%% formulas exist for the base of the natural %%% logarithm, e = \exp(1) ~= 2.718281828.... %%% %%% A long-standing, but still unproved, %%% conjecture, understandable even to a grade %%% school student, is that the digits of pi form %%% a random sequence: that is, in a sufficiently %%% large digit sequence, the digits each occur %%% with equal probability. Such a number is %%% called a ``normal number''. Note that this %%% does NOT mean that short digit sequences are %%% random: the sequences 0123456789 and %%% 7777777777 both occur within the first %%% 22,900,000,000 decimal digits of pi. The %%% six-digit sequence 999999 appears at the 762nd %%% decimal place, and is called the ``Feynman %%% point'', after Physics Nobel laureate Richard %%% Feynman: for background, see %%% %%% http://en.wikipedia.org/wiki/Feynman_point %%% %%% Normality has been proven for some other %%% irrational constants, but never for pi. %%% Statistical analysis of the known computed %%% digits of pi strongly suggest normality, but %%% a mathematical proof remains elusive, and %%% appears at present to be very difficult. %%% %%% See entries Marsaglia:2005:RPO and %%% Marsaglia:2006:RCS for remarks on statistical %%% measures of the randomness of digits of pi, %%% and how many such proposed measures are %%% seriously flawed. The second of those %%% articles concludes with this remark about %%% tests of randomness: ``$\pi$ sails through %%% all of them''. %%% %%% The checksum field above contains a CRC-16 %%% checksum as the first value, followed by the %%% equivalent of the standard UNIX wc (word %%% count) utility output of lines, words, and %%% characters. This is produced by Robert %%% Solovay's checksum utility.", %%% } %%% ==================================================================== @Preamble{ "\def \cprime {$'$}" # "\ifx \undefined \arccot \def \arccot{{\rm arccot}} \fi" # "\ifx \undefined \mathbb \def \mathbb #1{{\bf #1}}\fi" # "\ifx \undefined \mathbf \def \mathbf #1{{\bf #1}}\fi" # "\ifx \undefined \mathrm \def \mathrm #1{{\rm #1}}\fi" } %%% ==================================================================== %%% Acknowledgement abbreviations: @String{ack-nhfb= "Nelson H.

Mr. Lindemann (see also JFM 14.0369.02, JFM 14.0369.03) extends the conclusions made here and arrives at the following sentence: ``If $$f_1 (z) = 0, f_2 (z) = 0, \ldots, f_s (z) = 0$$ $s$ are irreducible algebraic equations of the form $$z^{n} + a_1z^{n-1} \ldots + a_n = 0$$, where $a_1$, $a_2$, $\ldots$ $a_n$ are whole numbers, and $z_i$, $z_i'$, $z_i''$, $\ldots$ are roots of the equation $f_i(z) = 0$, and $$\varsigma e^{z_i} = e^{z_i} + e^{z_i '} + e^{z_i ' '} + \ldots$$, where $N_0$, $N_1$, $\ldots$, $N_s$ are arbitrary nonzero whole numbers, then a relation of the form $$0 = N_0 + N_1 \varsigma e^{z_1} + N_2 \ varSigma e^{z_2} + \cdots + N_s \varsigma e^{z_s}$$ does not exist, unless one of the values $z$ is zero.\par If one replaces the equations $f_i (z) = 0$ by those irreducible equations for which the numbers $$Z_1 = z_1, Z_2 = z_1 + z_2, Z_3 = z_1 + z_2 + z_3, \ldots, Z_n = z_1 + z_2 \cdots + z_n$$ are satisfied, then this is a special case of the sentence: ``If $z$ one of zero different rational or algebraically irrational numbers, then $e^{\tau}$ is always transcendental. ``Thus, it is proven that the Ludolph number of $\pi$ is a transcendental number. The aforementioned theorem holds, if one of the $N_i$ is not whole or rational, but instead, is an arbitrary algebraic-irrational number. It similarly follows from the above statement that: `One concludes that if $N_0$, $N_1$, $\ldots$, $N_n$ are arbitrary, and if $z_0$, $z_1$, $\ldots$, $z_n$ are arbitrary, different (real or complexe) algebraic numbers, then a relation of the form $$0 = N_0e^{z_0} + N_1e^{z_1} + \cdots + N_n e^{z_n}$$ cannot exist, unless $N_i$ is zero", acknowledgement = ack-nhfb, fjournal = "Mathematische Annalen", language = "German", remark = "Improve the crude English translation of the abstract!", xxjournal = "Klein Ann.", } @Article{Glaisher:1883:CHL, author = "J.

The aim of this article is to suggest the most natural random number generator of all, the decimals of $\pi$, as a unique source of random numbers. There is no cyclic behaviour, all finite dimensional distributions of the sequence are uniform, so that it satisfies all the properties of today's generation of statistical tests; because of the manner in which the numbers are generated it is conjectured that it will satisfy any further test with probability one.

Let $ x = (x_{1}, \ldots, x_{n})$ be a vector in ${\mathbb{K}}^{n}$. The vector $x$ has an integer relation if there exists a vector $m = (m_{1}, \ldots, m_{n}) \in {\mathbb{O}}({\mathbb{K}})^{n}$, $m \ne 0$, such that $m_{1} x_{1} + m_{2} x_{2} + \ldots + m_{n} x_{n} = 0$. In this paper we define the parameterized integer relation construction algorithm PSLQ$(\tau)$, where the parameter $\tau $ can be freely chosen in a certain interval. Beginning with an arbitrary vector $x = (x_{1}, \ldots, x_{n}) \in {\mathbb{K}}^{n}$, iterations of PSLQ$(\tau)$ will produce lower bounds on the norm of any possible relation for $x$. Thus PSLQ$(\tau)$ can be used to prove that there are no relations for $x$ of norm less than a given size. Let $M_{x}$ be the smallest norm of any relation for $x$. For the real and complex case and each fixed parameter $\tau $ in a certain interval, we prove that PSLQ$(\tau)$ constructs a relation in less than $O(n^{3} + n^{2} \log M_{x})$ iterations.", acknowledgement = ack-nhfb, fjournal = "Mathematics of Computation", journal-URL = "http://www.ams.org/mcom/", } @Misc{Gourdon:1999:PEU, author = "X.

As an application, we give fast methods for evaluating the elementary functions $\log(x)$, $\exp(x)$, $\sin(x)$ etc. to high precision. For example, if $x$ is a positive floating-point number with an $n$-bit fraction, then (under rather weak assumptions) an $n$-bit approximation to $\log(x)$ or $\exp(x)$ may be computed in time asymptotically equal to $13 M(n) \lg(n)$, where $M(n)$ is the time required to multiply floating-point numbers with $n$-bit fractions. Similar results are given for the other elementary functions. Some analogies with operations on formal power series (over a field of characteristic zero) are discussed. In particular, it is possible to compute the first $n$ terms in $\log(1 + a_1 x + \cdots)$ or $\exp(a_1.x) + \cdots$ in time $O(M(n))$, where $M(n)$ is the time required to multiply two polynomials of degree $n - 1$. It follows that the first $n$ terms in a $q$-th power $(1 + a_1 x + \cdots)^q$ can be computed in time $O(M(n))$, independent of $q$. One of the results of this paper is the ``Gauss--Legendre'' or ``Brent--Salamin'' algorithm for computing pi. This is the first quadratically convergent algorithm for pi.

Many mathematical functions, such as trigonometric functions, can be partly or entirely expressed in terms of them. In most cases this allows efficient evaluation of such functions, their derivatives and their integrals. They are also the most efficient way known to compute constants, such as $ \pi $ and $e$, to high precision. Binary splitting is a low complexity algorithm for summing up hypergeometric series. It is a divide-and-conquer algorithm and can therefore be parallelized. However, it requires large number arithmetic, increases memory usage, and exhibits asymmetric workload, which makes it non-trivial to parallelize. We describe a high performing parallel implementation of the binary splitting algorithm for summing hypergeometric series on shared-memory multicores. To evaluate the implementation we have computed $ \pi $ to 5 trillion digits in August 2010 and 10 trillion digits in October 2011 both of which were new world records.
