  2. Casting out nines - Wikipedia

    en.wikipedia.org/wiki/Casting_out_nines

    Casting out nines is any of three arithmetical procedures: [1] Adding the decimal digits of a positive whole number , while optionally ignoring any 9s or digits which sum to 9 or a multiple of 9.

  3. Method of complements - Wikipedia

    en.wikipedia.org/wiki/Method_of_complements

    The smaller numbers, for use when subtracting, are the nines' complement of the larger numbers, which are used when adding. In mathematics and computing , the method of complements is a technique to encode a symmetric range of positive and negative integers in a way that they can use the same algorithm (or mechanism ) for addition throughout ...

  4. Nines (notation) - Wikipedia

    en.wikipedia.org/wiki/Nines_(notation)

    1 troy ounce of four nines fine gold (999.9) Nines are an informal logarithmic notation for proportions very near to one or, equivalently, percentages very near 100%. Put simply, "nines" are the number of consecutive nines in a percentage such as 99% (two nines) [1] or a decimal fraction such as 0.999 (three nines).

  5. Digit sum - Wikipedia

    en.wikipedia.org/wiki/Digit_sum

    For divisibility by 9, this test is called the rule of nines and is the basis of the casting out nines technique for checking calculations. Digit sums are also a common ingredient in checksum algorithms to check the arithmetic operations of early computers. [ 3 ]

  6. High availability - Wikipedia

    en.wikipedia.org/wiki/High_availability

    A simple mnemonic rule states that 5 nines allows approximately 5 minutes of downtime per year. Variants can be derived by multiplying or dividing by 10: 4 nines is 50 minutes and 3 nines is 500 minutes. In the opposite direction, 6 nines is 0.5 minutes (30 sec) and 7 nines is 3 seconds.

  8. Six nines in pi - Wikipedia

    en.wikipedia.org/wiki/Six_nines_in_pi

    A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [ 1 ] [ 2 ] It has become famous because of the mathematical coincidence , and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational .

    1 troy ounce (31 g) of four nines fine gold (999,9) Numbers very close to, but below one are often expressed in "nines" (N – not to be confused with the unit newton), that is in the number of nines following the decimal separator in writing the number in question. For example, "three nines" or "3N" indicates 0.999 or 99.9%, "four nines five ...
