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 ...
Perl supports hard references, which function similarly to those in other languages, and symbolic references, which are just string values that contain the names of variables. When a value that is not a hard reference is dereferenced, Perl considers it to be a symbolic reference and gives the variable with the name given by the value. [ 3 ]
Area c is the variance that the independent variable and the dependent variable have in common with the mediator, and this is the indirect effect. [ citation needed ] [ clarification needed ] Area c corresponds to the product of coefficients ( αβ ) and to ( τ − τ ' ).
In place of a named cell, an alternative approach is to use a cell (or grid) reference. Most cell references indicate another cell in the same spreadsheet, but a cell reference can also refer to a cell in a different sheet within the same spreadsheet, or (depending on the implementation) to a cell in another spreadsheet entirely, or a value ...
In computing, a null pointer or null reference is a value saved for indicating that the pointer or reference does not refer to a valid object. Programs routinely use null pointers to represent conditions such as the end of a list of unknown length or the failure to perform some action; this use of null pointers can be compared to nullable types ...
Before and after photos of the deadly wildfires in the Los Angeles area have sent tens of thousands scrambling for safety and decimated neighborhoods.
World Trade Organization members failed to agree on reforms to revive a broken trade dispute settlement system during the last General Council meeting before U.S. President-elect Donald Trump ...
In indirect reference counting, it is necessary to keep track of the reference's source. This means that two references are kept to the object: a direct one which is used for invocations; and an indirect one which forms part of a diffusion tree, such as in the Dijkstra–Scholten algorithm, which allows a garbage collector to identify dead ...
