2. Numeric precision in Microsoft Excel - Wikipedia

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

   Excel graph of the difference between two evaluations of the smallest root of a quadratic: direct evaluation using the quadratic formula (accurate at smaller b) and an approximation for widely spaced roots (accurate for larger b). The difference reaches a minimum at the large dots, and round-off causes squiggles in the curves beyond this minimum.

3. Precision and recall - Wikipedia

   en.wikipedia.org/wiki/Precision_and_recall

   In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).

4. Unit in the last place - Wikipedia

   en.wikipedia.org/wiki/Unit_in_the_last_place

   Here we start with 0 in single precision (binary32) and repeatedly add 1 until the operation does not change the value. Since the significand for a single-precision number contains 24 bits, the first integer that is not exactly representable is 2 24 +1, and this value rounds to 2 24 in round to nearest, ties to even.

5. Bootstrapping (statistics) - Wikipedia

   en.wikipedia.org/wiki/Bootstrapping_(statistics)

   Bootstrapping assigns measures of accuracy (bias, variance, confidence intervals, prediction error, etc.) to sample estimates. [2] [3] This technique allows estimation of the sampling distribution of almost any statistic using random sampling methods. [1]

6. Help:Displaying a formula - Wikipedia

   en.wikipedia.org/wiki/Help:Displaying_a_formula

   The visual editor shows a button that allows to choose one of three offered modes to display a formula. There are three methods for displaying formulas in Wikipedia: raw HTML , HTML with math templates (abbreviated here as {{ math }} ), and a subset of LaTeX implemented with the HTML markup < math ></ math > (referred to as LaTeX in this article).

7. Formula editor - Wikipedia

   en.wikipedia.org/wiki/Formula_editor

   A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.

8. Visual Basic for Applications - Wikipedia

   en.wikipedia.org/wiki/Visual_Basic_for_Applications

   Code written in VBA is compiled [6] to Microsoft P-Code (pseudo-code), a proprietary intermediate language, which the host applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams.

9. Floating point operations per second - Wikipedia

   en.wikipedia.org/wiki/Floating_point_operations...

   As of 2010 the fastest PC processor reached 109 gigaFLOPS (Intel Core i7 980 XE) [51] in double precision calculations. GPUs are considerably more powerful. For example, Nvidia Tesla C2050 GPU computing processors perform around 515 gigaFLOPS [ 52 ] in double precision calculations, and the AMD FireStream 9270 peaks at 240 gigaFLOPS.
