natural logarithm base

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

' 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"

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,
