Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within.
A function is a rule that, given one number, produces another number. [33] An example is the function producing the x-th power of b from any real number x, where the base b is a fixed number. This function is written as f(x) = b x.
While Microsoft Excel maintains the 1900 Leap year bug, Google sheets 'fixes' this bug by increasing all dates before March 1, 1900, so entering "0" and formatting it as a date returns December 30, 1899. On the other hand. Excel interprets "0" as meaning December 31, 1899, which is formatted to read January 0, 1900.
An infinite series of any rational function of can be reduced to a finite series of polygamma functions, by use of partial fraction decomposition, [8] as explained here. This fact can also be applied to finite series of rational functions, allowing the result to be computed in constant time even when the series contains a large number of terms.
About 68% of values drawn from a normal distribution are within one standard deviation σ from the mean; about 95% of the values lie within two standard deviations; and about 99.7% are within three standard deviations. [8] This fact is known as the 68–95–99.7 (empirical) rule, or the 3-sigma rule.
All superlative indices produce similar results and are generally the favored formulas for calculating price indices. [14] A superlative index is defined technically as "an index that is exact for a flexible functional form that can provide a second-order approximation to other twice-differentiable functions around the same point." [15]
The visual editor shows a button that allows to choose one of three offered modes to display a formula. There are three methods for displaying formulas in Wikipedia: raw HTML , HTML with math templates (abbreviated here as {{ math }} ), and a subset of LaTeX implemented with the HTML markup < math ></ math > (referred to as LaTeX in this article).
