  2. Integer - Wikipedia

    en.wikipedia.org/wiki/Integer

    Other integer data types are implemented with a fixed size, usually a number of bits which is a power of 2 (4, 8, 16, etc.) or a memorable number of decimal digits (e.g., 9 or 10). Cardinality The set of integers is countably infinite , meaning it is possible to pair each integer with a unique natural number.

  3. Elias omega coding - Wikipedia

    en.wikipedia.org/wiki/Elias_omega_coding

    To decode an Elias omega-encoded positive integer: Start with a variable N, set to a value of 1. If the next bit is a "0" then stop. The decoded number is N. If the next bit is a "1" then read it plus N more bits, and use that binary number as the new value of N. Go back to Step 2.

  4. Data recovery - Wikipedia

    en.wikipedia.org/wiki/Data_recovery

    The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.

    en.wikipedia.org/wiki/Python_(programming_language)

    Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...

    Idempotence (UK: / ˌ ɪ d ɛ m ˈ p oʊ t ən s /, [1] US: / ˈ aɪ d ə m-/) [2] is the property of certain operations in mathematics and computer science whereby they can be applied multiple times without changing the result beyond the initial application.

  7. Smooth number - Wikipedia

    en.wikipedia.org/wiki/Smooth_number

    This definition includes numbers that lack some of the smaller prime factors; for example, both 10 and 12 are 5-smooth, even though they miss out the prime factors 3 and 5, respectively. All 5-smooth numbers are of the form 2 a × 3 b × 5 c , where a , b and c are non-negative integers.

    The definition: A real number is algebraic if it’s the root of some polynomial with integer coefficients. For example, x²-6 is a polynomial with integer coefficients, since 1 and -6 are integers.

  9. Abundant number - Wikipedia

    en.wikipedia.org/wiki/Abundant_number

    Demonstration, with Cuisenaire rods, of the abundance of the number 12. In number theory, an abundant number or excessive number is a positive integer for which the sum of its proper divisors is greater than the number.
