Logarithms can be used to make calculations easier. For example, two numbers can be multiplied just by using a logarithm table and adding. These are often known as logarithmic properties, which are documented in the table below. [2] The first three operations below assume that x = b c and/or y = b d, so that log b (x) = c and log b (y) = d.
In computer science, a math library (or maths library) is a component of a programming language's standard library containing functions (or subroutines) for the most common mathematical functions, such as trigonometry and exponentiation. Bit-twiddling and control functionalities related to floating point numbers may also be included (such as in C).
Yongge Wang (1996) showed that the law of the iterated logarithm holds for polynomial time pseudorandom sequences also. [12] [13] The Java-based software testing tool tests whether a pseudorandom generator outputs sequences that satisfy the LIL. Balsubramani (2014) proved a non-asymptotic LIL that holds over finite-time martingale sample paths ...
Dedicated to the discrete logarithm in (/) where is a prime, index calculus leads to a family of algorithms adapted to finite fields and to some families of elliptic curves. The algorithm collects relations among the discrete logarithms of small primes, computes them by a linear algebra procedure and finally expresses the desired discrete ...
"On the Efficiency of Pollard's Rho Method for Discrete Logarithms". Conferences in Research and Practice in Information Technology, Vol. 77. The Australasian Theory Symposium (CATS2008). Wollongong. pp. 125– 131. Describes the improvements available from different iteration functions and cycle-finding algorithms.
In computer science, lg * is often used to indicate the binary iterated logarithm, which iterates the binary logarithm (with base ) instead of the natural logarithm (with base e). Mathematically, the iterated logarithm is well defined for any base greater than e 1 / e ≈ 1.444667 {\displaystyle e^{1/e}\approx 1.444667} , not only for base 2 ...
The following is a list of integrals (antiderivative functions) of logarithmic functions. For a complete list of integral functions, see list of integrals. Note: x > 0 is assumed throughout this article, and the constant of integration is omitted for simplicity.
