    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 ...

    en.wikipedia.org/wiki/Help:Sortable_tables

    A plus sign after a number breaks default numerical sorting if it is in one of the first 5 cells in a column. A plus sign in an otherwise empty cell breaks default numerical sorting of a column. That is if the cell is one of the first 5 cells in the column. You can also use 2 columns for a range if you want to sort by either the lower or upper ...

    Change "m" to the number of the column minus 1. 2nd column from the left would be "1". 3rd column from the left would be "2". The row number column created by Template:Static row numbers is not counted in these calculations. Fill in the "replace with" box with: $1[[$3]]$4. Then click "Replace all".

    In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using ...

    The arrays V and COL_INDEX are of length NNZ, and contain the non-zero values and the column indices of those values respectively; COL_INDEX contains the column in which the corresponding entry V is located. The array ROW_INDEX is of length m + 1 and encodes the index in V and COL_INDEX where the given row starts.

  7. Leading zero - Wikipedia

    en.wikipedia.org/wiki/Leading_zero

    A leading zero is any 0 digit that comes before the first nonzero digit in a number string in positional notation. [1] For example, James Bond 's famous identifier, 007, has two leading zeros. [ 2 ] Any zeroes appearing to the left of the first non-zero digit (of any integer or decimal) do not affect its value, and can be omitted (or replaced ...

  9. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    If it is the rough estimation, then only the first three non-zero digits are significant since the trailing zeros are neither reliable nor necessary; 45600 m can be expressed as 45.6 km or as 4.56 × 10 4 m in scientific notation, and neither expression requires the trailing zeros. An exact number has an infinite number of significant figures.
