  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    In digital logic, a lookup table can be implemented with a multiplexer whose select lines are driven by the address signal and whose inputs are the values of the elements contained in the array. These values can either be hard-wired, as in an ASIC whose purpose is specific to a function, or provided by D latches which allow for configurable values.

  3. Microsoft Excel - Wikipedia

    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 in the second line has only eleven 1's after the decimal, the difference when 1 is subtracted from this displayed value is three 0's followed by a string of eleven 1's.

  4. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    The key feature of spreadsheets is the ability for a formula to refer to the contents of other cells, which may, in turn, be the result of a formula. To make such a formula, one replaces a number with a cell reference. For instance, the formula =5*C10 would produce the

  5. Vinculum (symbol) - Wikipedia

    en.wikipedia.org/wiki/Vinculum_(symbol)

    A vinculum can indicate a line segment where A and B are the endpoints: ¯. A vinculum can indicate the repetend of a repeating decimal value: . 1 ⁄ 7 = 0. 142857 = 0.1428571428571428571...

  6. Cut, copy, and paste - Wikipedia

    en.wikipedia.org/wiki/Cut,_copy,_and_paste

    Inspired by early line and character editors, such as Pentti Kanerva's TV-Edit, [4] that broke a move or copy operation into two steps—between which the user could invoke a preparatory action such as navigation—Lawrence G. "Larry" Tesler proposed the names "cut" and "copy" for the first step and "paste" for the second step.

  7. Line number - Wikipedia

    en.wikipedia.org/wiki/Line_number

    The most common method of assigning numbers to lines is to assign every line a unique number, starting at 1 for the first line, and incrementing by 1 for each successive line. In the C programming language the line number of a source code line is one greater than the number of new-line characters read or introduced up to that point. [1]

  8. Overline - Wikipedia

    en.wikipedia.org/wiki/Overline

    The vinculum can indicate a line segment: [4] ¯ The vinculum can indicate a repeating decimal value: = ¯ = When it is not possible to format the number so that the overline is over the digit(s) that repeat, one overline character is placed to the left of the digit(s) that repeat: 3.

  9. Vertical line test - Wikipedia

    en.wikipedia.org/wiki/Vertical_line_test

    A function can only have one output, y, for each unique input, x. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function. If all vertical lines intersect a curve at most once then the curve represents a function. [1]
