natural logarithm of number

Introduction In 1982, tateaki. Sasaki and yasumasa Kanada published a paper: practically Fast Multiple-Precision Evaluation of log (X ). In this four-page paper, they introduced a quick way to calculate the natural logarithm.Algorithm. C # Program

IntroductionSome time ago. I wrote two essays on algorithms for calculating natural logarithms, using the elliptical θ function-arithmetic geometric averaging and Taylor series expansions.So what about the performance of the two algorithms? In the

Java logarithmic functions and Java logarithm operations2010-05-17 10:32 China it lab anonymous Keyword: Java Java logarithmic functions are computationally problematic, but there are amazing errors in the API. But if you use the following method,

' e=1+1/1! +1/2! +1/3! +1/4! +......+1/n! ' Φkρ=αe ' Wherein, alpha and k are constants, φ is polar, and rho is the polar diameter, and E is the base of the natural logarithm. For the sake of discussion, we define e or the form of "natural law"

WPS Table The method of finding the value of natural logarithm e: Open the WPS table and create a new workbook. A1 Enter the n value, B1 to find the E value. Because e is an irrational number, you need to pull B a little wider. In B1

The R language is very powerful and can be used to calculate various types of exponential functions.For example, suppose Y=a^x, seeking x.Function:Log (P1 [, p2])Where P1 is the power, P2 is the base, if P2 does not exist, then the base is E, the

This article mainly introduces the use of logarithm Math in JavaScript. the log () method tutorial is the basic knowledge in getting started with JS. If you need it, you can refer to this method to return the natural logarithm of a number (the base

In the tutorial of using the logarithm Math. log () method in JavaScript, javascriptmath. log This method returns the natural logarithm of a number (the base number is E ). If the number value is negative, the return value is always

The Fibonacci sequence , also known as the Golden Section , refers to a sequence of numbers 0, 1, 1, 2, 3, 5, 8, 13, and 、...... In mathematics, the Fibonacci sequence is defined as follows : F (0) =0,f (1) =1,f (n) =f (n-1) +f (n-2) (n≥2,n∈n*) in

Natural language Processing--TF-IDF algorithm to extract key words This headline seems to be very complicated, in fact, I would like to talk about a very simple question. There is a very long article, I want to use the computer to extract its
