    Here the 'IEEE 754 double value' resulting of the 15 bit figure is 3.330560653658221E-15, which is rounded by Excel for the 'user interface' to 15 digits 3.33056065365822E-15, and then displayed with 30 decimals digits gets one 'fake zero' added, thus the 'binary' and 'decimal' values in the sample are identical only in display, the values ...

    Like other parameters, colors can also be specified for a whole row or the whole table; parameters for a row override the value for the table, and those for a cell override those for a row. There is no easy way to specify a color for a whole column: each cell in the column must be individually specified.

    The data cell wikitext needs to be on a separate line from the row header cell for that row. See the next table. To make this happen use Excel2Wiki.

  7. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    The concept of rounding is very old, perhaps older than the concept of division itself. Some ancient clay tablets found in Mesopotamia contain tables with rounded values of reciprocals and square roots in base 60. [40] Rounded approximations to π, the length of the year, and the length of the month are also ancient – see base 60 examples.

    This process works most of the time but can also easily get confused if you have inconsistent values or additional specifiers that the system doesn't know about. To avoid this ambiguity you can force a particular data type or override the value of a cell. For numeric values, consider using template {}, see examples at Template:Val § Sorting.

  9. Interval arithmetic - Wikipedia

    en.wikipedia.org/wiki/Interval_arithmetic

    The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
