  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    With some exceptions regarding erroneous values, infinities, and denormalized numbers, Excel calculates in double-precision floating-point format from the IEEE 754 specification [1] (besides numbers, Excel uses a few other data types [2] ). Although Excel allows display of up to 30 decimal places, its precision for any specific number is no ...

  3. Semi-empirical mass formula - Wikipedia

    en.wikipedia.org/wiki/Semi-empirical_mass_formula

    Nuclear physics. In nuclear physics, the semi-empirical mass formula ( SEMF) (sometimes also called the Weizsäcker formula, Bethe–Weizsäcker formula, or Bethe–Weizsäcker mass formula to distinguish it from the Bethe–Weizsäcker process) is used to approximate the mass of an atomic nucleus from its number of protons and neutrons.

  4. Mode (statistics) - Wikipedia

    en.wikipedia.org/wiki/Mode_(statistics)

    Mode (statistics) In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmaxxi P (X = xi) ). In other words, it is the value that is most likely to be sampled.

  5. Pairing (computing) - Wikipedia

    en.wikipedia.org/wiki/Pairing_(computing)

    Pairing, sometimes known as bonding, is a process used in computer networking that helps set up an initial linkage between computing devices to allow communications between them. The most common example is used in Bluetooth, where the pairing process is used to link devices like a Bluetooth headset with a mobile phone . Categories:

  6. Approximations of π - Wikipedia

    en.wikipedia.org/wiki/Approximations_of_π

    In other words, begin by choosing a value for r. Consider all cells (x, y) in which both x and y are integers between − r and r. Starting at 0, add 1 for each cell whose distance to the origin (0,0) is less than or equal to r. When finished, divide the sum, representing the area of a circle of radius r, by r 2 to find the approximation of π.

  7. Integration by parts - Wikipedia

    en.wikipedia.org/wiki/Integration_by_parts

    t. e. In calculus, and more generally in mathematical analysis, integration by parts or partial integration is a process that finds the integral of a product of functions in terms of the integral of the product of their derivative and antiderivative.

  8. Langford pairing - Wikipedia

    en.wikipedia.org/wiki/Langford_pairing

    A Langford pairing for n = 4. In combinatorial mathematics, a Langford pairing, also called a Langford sequence, is a permutation of the sequence of 2 n numbers 1, 1, 2, 2, ..., n, n in which the two 1s are one unit apart, the two 2s are two units apart, and more generally the two copies of each number k are k units apart.

    A pairing is any R -bilinear map . That is, it satisfies. , and. for any and any and any . Equivalently, a pairing is an R -linear map. where denotes the tensor product of M and N . A pairing can also be considered as an R -linear map , which matches the first definition by setting . A pairing is called perfect if the above map is an ...
