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 ...
Excel 2.0 was released a month before Windows 2.0, and the installed base of Windows was so low at that point in 1987 that Microsoft had to bundle a runtime version of Windows 1.0 with Excel 2.0. [120] Unlike Microsoft Word, there never was a DOS version of Excel.
A spreadsheet does not have to contain any formulas at all, in which case it could be considered merely a collection of data arranged in rows and columns (a database) like a calendar, timetable, or simple list.
The first line of a row has "|-" at the beginning; the row is always two or more lines long; and a row continues until you see another line that starts "|-", indicating that the next row's starting. To test your understanding of editing tables, see if you can answer the following question: In Figure 14-13 , look at the last three rows in the table.
This is an injective relation: each combination of the values of the headers row (row 0, for lack of a better term) and the headers column (column 0 for lack of a better term) is related to a unique cell in the table: Column 1 and row 1 will only correspond to cell (1,1); Column 1 and row 2 will only correspond to cell (2,1) etc.
A column may contain text values, numbers, or even pointers to files in the operating system. [2] Columns typically contain simple types, though some relational database systems allow columns to contain more complex data types, such as whole documents, images, or even video clips. [3] [better source needed] A column can also be called an attribute.
Programs that work with CSV may have limits on the maximum number of rows CSV files can have. Below is a list of common software and its limitations: [34] Microsoft Excel: 1,048,576 row limit; Microsoft PowerShell, no row or cell limit. (Memory Limited) Apple Numbers: 1,000,000 row limit;
