logarithm base 2

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

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,

Like this common "ordinary" calculator, in fact everything can be counted (with the limit, what can become subtraction). Among them, the natural logarithm is especially good, this article will provide a method, mainly using the calculator's Open

' 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"

MathType is a powerful mathematical formula editor software that uses it to enter almost any mathematical formula and symbol you want, and can also be called directly after saving a commonly used formula, such as the input of a logarithmic function.

Because the topic requires two different colors to be adjacent to the same column, there is no effect between columns and columns, which can be dyed on a column-by-row basis.If a lattice above the adjacent lattice, has been dyed the lattice when

Base sorting introduction and Java implementation, base sorting introduction java Basic Ideas Base sorting (RadixSort) is developed on the basis of Bucket sorting, both of which are advanced implementations of distributed sorting. The basic idea of

There are several types of encryption in PHP:1. MD5 Encryptionstring MD5 string $str $raw _output false ] )ParametersSTR--the original string.Raw_output--If the optional raw_output is set to TRUE, then the MD5 Digest is returned in the original

Q: Array creation?A: There are two types of data in Java, basic types and object types, and in many programming languages (even object-oriented language C + +), arrays are basic types. In Java, however, the array is viewed as an object. Therefore,

2.1 What is an objectAll JavaScript data can be treated as objects, and each object has its attributes (properties) and methods (methods).An object's properties reflect certain properties of the object, such as the length of the string, the width of
