  2. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two , e.g. ⁠ 1 / 8 ⁠ = ⁠ 1 / 2 3 ⁠ .

  3. Dyadic rational - Wikipedia

    en.wikipedia.org/wiki/Dyadic_rational

    Dyadic rationals in the interval from 0 to 1. In mathematics, a dyadic rational or binary rational is a number that can be expressed as a fraction whose denominator is a power of two. For example, 1/2, 3/2, and 3/8 are dyadic rationals, but 1/3 is not.

  5. Khinchin's constant - Wikipedia

    en.wikipedia.org/wiki/Khinchin's_constant

    The proof presented here was arranged by Czesław Ryll-Nardzewski [3] and is much simpler than Khinchin's original proof which did not use ergodic theory.. Since the first coefficient a 0 of the continued fraction of x plays no role in Khinchin's theorem and since the rational numbers have Lebesgue measure zero, we are reduced to the study of irrational numbers in the unit interval, i.e ...

    When = 1 *the standard Pochhammer symbol and gamma function are obtained. Díaz and Pariguan use these definitions to demonstrate a number of properties of the hypergeometric function. Although Díaz and Pariguan restrict these symbols to > 0, the Pochhammer symbol as they define it is well-defined for all real k/ and for negative k gives the ...

    The evaluation of the full integral of a Gaussian function by trapezoidal rule with 1% accuracy can be made using just 4 points. [11] Simpson's rule requires 1.8 times more points to achieve the same accuracy. [11] [12]
