  2. Clamp (function) - Wikipedia

    en.wikipedia.org/wiki/Clamp_(function)

    In Python, the pandas library offers the Series.clip [1] and DataFrame.clip [2] methods. The NumPy library offers the clip [3] function. In the Wolfram Language, it is implemented as Clip [x, {minimum, maximum}]. [4] In OpenGL, the glClearColor function takes four GLfloat values which are then 'clamped' to the range [,]. [5]

  3. All nearest smaller values - Wikipedia

    en.wikipedia.org/wiki/All_nearest_smaller_values

    The first element of the sequence (0) has no previous value. The nearest (only) smaller value previous to 8 and to 4 is 0. All three values previous to 12 are smaller, but the nearest one is 4. Continuing in the same way, the nearest previous smaller values for this sequence (indicating the nonexistence of a previous smaller value by a dash) are

  4. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    In floating-point arithmetic, rounding aims to turn a given value x into a value y with a specified number of significant digits. In other words, y should be a multiple of a number m that depends on the magnitude of x. The number m is a power of the base (usually 2 or 10) of the floating-point representation.

  5. Almost integer - Wikipedia

    en.wikipedia.org/wiki/Almost_integer

    Ed Pegg Jr. noted that the length d equals (), which is very close to 7 (7.0000000857 ca.) [1] In recreational mathematics, an almost integer (or near-integer) is any number that is not an integer but is very close to one.

  6. Unit in the last place - Wikipedia

    en.wikipedia.org/wiki/Unit_in_the_last_place

    Here we start with 0 in single precision (binary32) and repeatedly add 1 until the operation does not change the value. Since the significand for a single-precision number contains 24 bits, the first integer that is not exactly representable is 2 24 +1, and this value rounds to 2 24 in round to nearest, ties to even.

  7. Predicted Aligned Error - Wikipedia

    en.wikipedia.org/wiki/Predicted_Aligned_Error

    Although PAE provides valuable information, users should note that it is asymmetric; the PAE value for (x, y) may differ from the value for (y, x), particularly between loop regions with highly uncertain orientations. [6]

  8. Floating-point arithmetic - Wikipedia

    en.wikipedia.org/wiki/Floating-point_arithmetic

    For example, the number 2469/200 is a floating-point number in base ten with five digits: / = = ⏟ ⏟ ⏞ However, 7716/625 = 12.3456 is not a floating-point number in base ten with five digits—it needs six digits. The nearest floating-point number with only five digits is 12.346.

  9. Ball tree - Wikipedia

    en.wikipedia.org/wiki/Ball_tree

    function knn_search is input: t, the target point for the query k, the number of nearest neighbors of t to search for Q, max-first priority queue containing at most k points B, a node, or ball, in the tree output: Q, containing the k nearest neighbors from within B if distance(t, B.pivot) - B.radius ≥ distance(t, Q.first) then return Q ...
