Numbers uses a hybrid approach to the creation of formulas, supporting the use of named data like Improv, but implementing them in-sheet like Excel. In basic operation, Numbers can be used just like Excel; data can be typed anywhere, and formulas can be created by referring to the data by its cell. However, if the user types a header into the ...
When the computer calculates a formula in one cell to update the displayed value of that cell, cell reference(s) in that cell, naming some other cell(s), causes the computer to fetch the value of the named cell(s). A cell on the same "sheet" is usually addressed as: =A1 A cell on a different sheet of the same spreadsheet is usually addressed as:
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 ...
Data Bars show as a gradient bar in the background of a cell the contribution of the cell value in the group. Column titles can optionally show options to control the layout of the column. Multithreaded calculation of formulae, to speed up large calculations, especially on multi-core/multi-processor systems.

Pull-to-refresh in the Wikipedia mobile app. Pull-to-refresh is a touchscreen gesture developed by Loren Brichter.It consists of touching the screen of a computing device with a finger or pressing a button on a pointing device, dragging the screen downward with the finger or pointing device, and then releasing it, as a signal to the application to refresh the contents of the screen.
The refresh cycle is similar to the read cycle, but executes faster for two reasons: For a refresh, only the row address is needed, so a column address doesn't have to be applied to the chip address circuits. Data read from the cells does not need to be fed into the output buffers or the data bus to send to the CPU.
A background process is a computer process that runs behind the scenes (i.e., in the background) and without user intervention. [1] Typical tasks for these processes include logging, system monitoring, scheduling, [ 2 ] and user notification.
