  2. Numeric precision in Microsoft Excel - Wikipedia

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

    In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using Excel. Because the sum has only eleven 1s after the decimal, the true difference when ‘1’ is subtracted is three 0s followed by a string of eleven 1s.

  3. Skip list - Wikipedia

    en.wikipedia.org/wiki/Skip_list

    To index the skip list and find the i'th value, traverse the skip list while counting down the widths of each traversed link. Descend a level whenever the upcoming width would be too large. For example, to find the node in the fifth position (Node 5), traverse a link of width 1 at the top level.

  4. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    The C++ Standard Library also supports for_each, [10] that applies each element to a function, which can be any predefined function or a lambda expression. While range-based for is only from the start to the end, the range or direction can be changed by altering the first two parameters.

  5. Conditional loop - Wikipedia

    en.wikipedia.org/wiki/Conditional_loop

    The following is a C-style While loop.It continues looping while x does not equal 3, or in other words it only stops looping when x equals 3.However, since x is initialized to 0 and the value of x is never changed in the loop, the loop will never end (infinite loop).

    Post-secondary students may obtain the university edition of Microsoft Office 365 subscription. It is limited to one user and two devices, plus the subscription price is valid for four years instead of just one. Apart from this, the university edition is identical in features to the Home Premium version.

  7. Systematic sampling - Wikipedia

    en.wikipedia.org/wiki/Systematic_sampling

    In one-dimensional systematic sampling, progression through the list is treated circularly, with a return to the top once the list ends. The sampling starts by selecting an element from the list at random and then every k th element in the frame is selected, where k, is the sampling interval (sometimes known as the skip): this is calculated as: [3]

  8. Stack (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Stack_(abstract_data_type)

    The programmable pocket calculator HP-42S from 1988 had, like nearly all of the company's calculators of that time, a 4-level-stack and could display two of four values of the stack registers X, Y, Z, and T at the same time due to its two-line display, here X and Y.

  9. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    Another very simple implementation technique, usable when the keys are restricted to a narrow range, is direct addressing into an array: the value for a given key k is stored at the array cell A[k], or if there is no mapping for k then the cell stores a special sentinel value that indicates the lack of a mapping. This technique is simple and ...
