  2. 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 ...

  3. 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.

  4. Trailing zero - Wikipedia

    en.wikipedia.org/wiki/Trailing_zero

    Trailing zero. In mathematics, trailing zeros are a sequence of 0 in the decimal representation (or more generally, in any positional representation) of a number, after which no other digits follow. Trailing zeros to the right of a decimal point, as in 12.340, don't affect the value of a number and may be omitted if all that is of interest is ...

  5. 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. Two's complement - Wikipedia

    en.wikipedia.org/wiki/Two's_complement

    Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, [1] and more generally, fixed point binary values. Two's complement uses the binary digit with the greatest value as the sign to indicate whether the binary number is positive or negative; when the most significant bit is 1 the number is signed as negative and when the most ...

  7. List of date formats by country - Wikipedia

    en.wikipedia.org/wiki/List_of_date_formats_by...

    Yes. Yes. Long formats: English: mmmm d, yyyy. DMY dates are also used occasionally, primarily by, but not limited to, government institutions such as on the data page of passports, and immigration and customs forms. Filipino: ika- d ng mmmm (,) yyyy [ 135] or a- d ng mmmm (,) yyyy.

  8. IBM hexadecimal floating-point - Wikipedia

    en.wikipedia.org/wiki/IBM_hexadecimal_floating-point

    Zero (0.0) is represented in normalized form as all zero bits, which is arithmetically the value +0.0 16 × 16 0 − 64 = +0 × 16 −64 ≈ +0.000000 × 10 −79 = 0. Given a fraction of all-bits zero, any combination of positive or negative sign bit and a non-zero biased exponent will yield a value arithmetically equal to zero.

  9. Block floating point - Wikipedia

    en.wikipedia.org/wiki/Block_floating_point

    The common exponent is found by data with the largest amplitude in the block. To find the value of the exponent, the number of leading zeros must be found (count leading zeros). For this to be done, the number of left shifts needed for the data must be normalized to the dynamic range of the processor used.
