Guy also formulated a second strong law of small numbers: When two numbers look equal, it ain't necessarily so! [3] Guy explains this latter law by the way of examples: he cites numerous sequences for which observing the first few members may lead to a wrong guess about the generating formula or law for the sequence.
In probability theory, a probability density function (PDF), density function, or density of an absolutely continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the ...
Law of small numbers may refer to: The Law of Small Numbers, a book by Ladislaus Bortkiewicz. Poisson distribution, the use of that name for this distribution originated in the book The Law of Small Numbers; Hasty generalization, a logical fallacy also known as the law of small numbers
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4] The parameters used are:

However, is not a binary64 floating-point number; the nearest one, which x will be initialized to in this fragment, is = +. Although the radix conversion from decimal floating-point to binary floating-point only incurs a small relative error, catastrophic cancellation may amplify it into a much larger one:
Richard Kenneth Guy (30 September 1916 – 9 March 2020) was a British mathematician. He was a professor in the Department of Mathematics at the University of Calgary. [1] He is known for his work in number theory, geometry, recreational mathematics, combinatorics, and graph theory.
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] The formula is:
