eulers-number

问题 For example, how would I go about entering the value e^2 in R? 回答1: The R expression exp(1) represents e, and exp(2) represents e^2. This works because exp is the exponentiation function with base e. 回答2: -digamma(1) is the Euler's Constant in R. e , ( exp(1) in R), which is the natural base of the natural logarithm Euler's Constant. Euler's Number 回答3: if you want to have a little number e to play with, you can also make one yourself: emake <- function(){ options("warn"=-1) e <- 0 for (n in

问题 My professor from Algorithms course gave me the following homework: Write a C/C++ program that calculates the value of the Euler's number (e) with a given accuracy of eps > 0. Hint: The number e = 1 + 1/1! +1/2! + ... + 1 / n! + ... = 2.7172 ... can be calculated as the sum of elements of the sequence x_0, x_1, x_2, ..., where x_0 = 1, x_1 = 1+ 1/1 !, x_2 = 1 + 1/1! +1/2 !, ..., the summation continues as long as the condition |x_(i+1) - x_i| >= eps is valid. As he further explained, eps is

问题 I am trying to find the more 'natural' way to use the number e in C/C++. I am focused on calculating the function e ^n. I think that 'cmath', by default, does not provide support for both (function and constant). However, it can be enabled to include constants defined by the compiler, in this case, M_E . This can be done by including the statement #define _USE_MATH_DEFINES . On the other hand, e can be defined as a constant: #define E 2.71828182845904523536; or const double EULER = 2

问题 I have a binary number represented as 11.1111111 (the . being analogous to a decimal point). There are 2 bits before the point, and 1024 bits after the point. It was an exercise in calculating e to a high level of precision, but now I am stuck as to how to convert it to decimal. Just in case you guys want to know the number, here it is: 10
