2. Numeric precision in Microsoft Excel - Wikipedia

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

   The inaccuracy in Excel calculations is more complicated than errors due to a precision of 15 significant figures. Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel ...

3. Spreadsheet - Wikipedia

   Use of named column variables x & y in Microsoft Excel. Formula for y=x 2 resembles Fortran, and Name Manager shows the definitions of x & y. In most implementations, a cell, or group of cells in a column or row, can be "named" enabling the user to refer to those cells by a name rather than by a grid reference.

7. Numbers (spreadsheet) - Wikipedia

   en.wikipedia.org/wiki/Numbers_(spreadsheet)

   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.

8. Haversine formula - Wikipedia

   en.wikipedia.org/wiki/Haversine_formula

   The haversine formula allows the haversine of θ (that is, hav (θ)) to be computed directly from the latitude (represented by φ) and longitude (represented by λ) of the two points: where. λ1, λ2 are the longitude of point 1 and longitude of point 2. Finally, the haversine function hav (θ), applied above to both the central angle θ and ...

9. Mode (statistics) - Wikipedia

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

   Mode (statistics) In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmaxxi P (X = xi) ). In other words, it is the value that is most likely to be sampled.
