Names must be unique within the spreadsheet, but when using multiple sheets in a spreadsheet file, an identically named cell range on each sheet can be used if it is distinguished by adding the sheet name. One reason for this usage is for creating or running macros that repeat a command across many sheets. Another reason is that formulas with ...
Some have claimed that Quattro Pro was the first to use the tabbed notebook metaphor, but another spreadsheet, Boeing Calc, used tabs to multiple sheets, and allowed three-dimensional references before Quattro Pro was on the market. (Boeing Calc was so slow that its multiple sheet capabilities were barely usable.) [1] [2]
Circular references can appear in computer programming when one piece of code requires the result from another, but that code needs the result from the first. For example, the two functions, posn and plus1 in the following Python program comprise a circular reference: [further explanation needed]
But because the ARM allocates both accrual reversals and cash effects to weeks or days, it is more complicated than the ANI or PBS indirect methods. The ARM is best suited to the medium-term forecasting horizon. [5] Both the ANI and PBS methods are suited to the medium-term (up to one year) and long-term (multiple years) forecasting horizons ...
The basic design of how graphics are represented in PDF is very similar to that of PostScript, except for the use of transparency, which was added in PDF 1.4. PDF graphics use a device-independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale, rotate, or skew graphical
The U.S. Government Accountability Office (GAO) defines a cost estimate as "the summation of individual cost elements, using established methods and valid data, to estimate the future costs of a program, based on what is known today". The GAO reports that "realistic cost estimating was imperative when making wise decisions in acquiring new ...
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 ...
In mathematics and computer science, Horner's method (or Horner's scheme) is an algorithm for polynomial evaluation.Although named after William George Horner, this method is much older, as it has been attributed to Joseph-Louis Lagrange by Horner himself, and can be traced back many hundreds of years to Chinese and Persian mathematicians.
