    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 ...

  3. Leading zero - Wikipedia

    en.wikipedia.org/wiki/Leading_zero

    Leading zeros are also present whenever the number of digits is fixed by the technical system (such as in a memory register), but the stored value is not large enough to result in a non-zero most significant digit. [7] The count leading zeros operation efficiently determines the number of leading zero bits in a machine word. [8]

  4. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    Zeros between two significant non-zero digits are significant (significant trapped zeros). 101.12003 consists of eight significant figures if the resolution is to 0.00001. 125.340006 has seven significant figures if the resolution is to 0.0001: 1, 2, 5, 3, 4, 0, and 0. Zeros to the left of the first non-zero digit (leading zeros) are not ...

  6. Find first set - Wikipedia

    en.wikipedia.org/wiki/Find_first_set

    The count trailing zeros operation would return 3, while the count leading zeros operation returns 16. The count leading zeros operation depends on the word size: if this 32-bit word were truncated to a 16-bit word, count leading zeros would return zero. The find first set operation would return 4, indicating the 4th position from the right.

  8. Row echelon form - Wikipedia

    en.wikipedia.org/wiki/Row_echelon_form

    All rows having only zero entries are at the bottom. [1] The leading entry (that is, the left-most nonzero entry) of every nonzero row, called the pivot, is on the right of the leading entry of every row above. [2] Some texts add the condition that the leading coefficient must be 1 [3] while others require this only in reduced row echelon form.

  9. 6174 - Wikipedia

    en.wikipedia.org/wiki/6174

    Select any four-digit number which has at least two different digits (leading zeros are allowed), Create two new four-digit numbers by arranging the original digits in a.) ascending and b.) descending order (adding leading zeros if necessary). Subtract the smaller number from the bigger number. If the result is not 6174, return to step 2 and ...
