Convert any decimal places into 2, 3, 4, 5, 6, 7, 8, and 9 decimal places, retain 8 digits after the decimal point, and output. For example, if the decimal point is 0.795, the output is:
Decimal decimal number: 0.795000Decimal decimal number: 0.795000Decimal decimal number: 0.795000Decimal decimal number: 0.795000Decimal decimal number: 0.795000Decimal decimal nu

Consider the function $ $f (t) =\int_{0}^{t}e^{-x^2}dx$$ Compute $f ({3\over2}) $ to within ${1\over2}$.Solution:Note that the Power series (Taylor series) of $e ^x$ is $ $e ^x=\sum_{n=0}^{\infty}{x^n\over n!} $$ Thus We have $ $e ^{-x^2}=\sum_{n=0}^{\infty}{{(-x^

Algorithm training 6-2 Recursive binary representation of digit time limit: 10.0s memory Limit: 256.0MB problem description Given a decimal integer, returns the number of bits of its corresponding binary number. For example, enter decimal number 9, which corresponds to a binary number of 1001, so the number of bits is 4. Sample input An input example that satisfi

Third, cross-site request forgeryFirst, IntroductionDjango provides users with the ability to prevent cross-site request forgery, which is accomplished through middleware django.middleware.csrf.CsrfViewMiddleware. For Django, the ability to set up anti-cross-site request forgery is divided into global and local.Global:Middleware Django.middleware.csrf.CsrfViewMiddlewareLocal:

6-2 insertion of ordered order table (10 points)
This requires the orderly insertion function of an ascending sequential table to be implemented. L is an ascending sequential order table, where the function status listinsert_sortedsq (SqList l, Elemtype e) is used to insert a data in an ascending order in the order table. For example: The original data is: 2 5,

then calculate the offset, and then control the read and write to the pixel, we are lazy here, with the array way of access, in fact, and the starting address plus offset is the same ha.It can be found that we did not use data[i*img->widthstep+j] = 0;, but instead used Cv_image_elem (IMG, unsigned char, I, j) = 0; Cv_image_elem is a macro, it helps us to encapsulate the next, it is very simple to use, so it is used, its definition in the types_c.h inside, its macro definition is as follows:1 /*
