    In this example, only the values in the A column are entered (10, 20, 30), and the remainder of cells are formulas. 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.

    en.wikipedia.org/wiki/List_coloring

    For a graph G, let χ(G) denote the chromatic number and Δ(G) the maximum degree of G.The list coloring number ch(G) satisfies the following properties.. ch(G) ≥ χ(G).A k-list-colorable graph must in particular have a list coloring when every vertex is assigned the same list of k colors, which corresponds to a usual k-coloring.

  4. Numeric precision in Microsoft Excel - Wikipedia

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

    In the top figure the fraction 1/9000 in Excel is displayed. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. 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 ...

  5. Help:Sortable tables - Wikipedia

    en.wikipedia.org/wiki/Help:Sortable_tables

    When a column contains repeated values, sorting the column should maintain the original order of rows within each subset that shares the same value. This is known as stable sorting. As a result, multi-key sorting (sorting by primary, secondary, tertiary keys, etc.) can be achieved by sorting the least significant key first and the most ...

    en.wikipedia.org/wiki/List_of_colors:_N–Z

    Some environments (like Microsoft Excel) reverse the order of bytes in hex color values (i.e. to "BGR"). Colors that appear on the web-safe color palette—which includes the sixteen named colors—are noted. [1] (Those four named colors corresponding to the neutral greys have no hue value, which is effectively ignored—i.e., left blank.)

  7. Soundex - Wikipedia

    en.wikipedia.org/wiki/Soundex

    Soundex is the most widely known of all phonetic algorithms (in part because it is a standard feature of popular database software such as IBM Db2, PostgreSQL, [2] MySQL, [3] SQLite, [4] Ingres, MS SQL Server, [5] Oracle, [6] ClickHouse, [7] Snowflake [8] and SAP ASE. [9]) Improvements to Soundex are the basis for many modern phonetic algorithms.

  8. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    When one of the components has the strongest intensity, the color is a hue near this primary color (red-ish, green-ish, or blue-ish), and when two components have the same strongest intensity, then the color is a hue of a secondary color (a shade of cyan, magenta, or yellow). A secondary color is formed by the sum of two primary colors of equal ...

    en.wikipedia.org/wiki/X11_color_names

    The web colors list is descended from it but differs for certain color names. [1] Color names are not standardized by Xlib or the X11 protocol. The list does not show continuity either in selected color values or in color names, and some color triplets have multiple names. Despite this, graphic designers and others got used to them, making it ...
