Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...
A logical spreadsheet is a spreadsheet in which formulas take the form of logical constraints rather than function definitions.. In traditional spreadsheet systems, such as Excel, cells are partitioned into "directly specified" cells and "computed" cells and the formulas used to specify the values of computed cells are "functional", i.e. for every combination of values of the directly ...
A cell on a different sheet of the same spreadsheet is usually addressed as: =SHEET2!A1 (that is; the first cell in sheet 2 of the same spreadsheet). Some spreadsheet implementations in Excel allow cell references to another spreadsheet (not the currently open and active file) on the same computer or a local network.
Excel offers many user interface tweaks over the earliest electronic spreadsheets; however, the essence remains the same as in the original spreadsheet software, VisiCalc: the program displays cells organized in rows and columns, and each cell may contain data or a formula, with relative or absolute references to other cells. Excel 2.0 for ...
A primality test is an algorithm for determining whether an input number is prime.Among other fields of mathematics, it is used for cryptography.Unlike integer factorization, primality tests do not generally give prime factors, only stating whether the input number is prime or not.
It features Excel Web Access, the client-side component which is used to render the worksheet on a browser, Excel Calculation Service which is the server side component which populates the worksheet with data and perform calculations, and Excel Web Services that extends Excel functionalities into individual web services.
The last four column vectors belong to the A × B interaction, as their entries depend on the values of both factors, and as all four columns are orthogonal to the columns for A and B. The latter can be verified by taking dot products. A 2 × 2 × 2 experiment: This will have 1 degree of freedom for every main effect and interaction. For ...
Any pair of the first four columns contains each of the ordered pairs (0, 0), (0, 1), (1, 0) and (1, 1) two times. Columns 4 and 5 – or column 5 with any one of the other columns – contains each ordered pair (i, j) once, where i = 0 or 1 and j = 0, 1, 2, or 3. It may thus be denoted may be denoted OA(8, 5, 2 4 4 1, 2), as is discussed below ...
