log10

On the msdn machine, log10 and power functions are reversely related to each other. For example, 10 ^ log10 (n) = n. There is no problem when there is only one value. The result set is shown below .; With CAS (select number from master .. spt_values

Today, my classmates asked me if there is any simple way to find out the sum of two numbers in C + +, then there is a way to title.The return value of LOG10 (100) is the return value of 2,log (999) is more, but if you position the return value int,

This question requires the number of bits of the factorial of N, if n is larger, the factorial of n is bound to be aA large number, the title said 1The factorial would be a very huge number, for dealing with large numbers of problems, IWe usually

  Project Euler problem 57     This requires in-depth research .... I wrote it violently .. Sorry... Change later... We are also looking at the continuous score recently .. But it is still too busy .. The following is a discussion in the Forum ..

Law one: The logarithm of a number, +1 rounding is its number of digitsProblem converted to int (log10 (n!) +1), logarithmic property log10 (n!) =LOG10 (N) +log10 (N-1) +...+log10 (1)/* Use LOG10 to find the number of digits */#include #include int

Ask N. The number of digits The main learning today is the Stirling formula:log10 (sqrt (2.0*pi*n)) +n*log10 (n/e)Problem Solving Ideas:Two methods of solution1:1+LG (1) +LG (2) +. +LG (N)2:strling formula.Method One:Analysis:The title means to give

The first is the solution to violence. Note that it is not the essence of violence, but relative violence:F (n) = log10 (1*2*3*4 *...... * N) + 1 = log10 (1) + log10 (2) + log10 (3) + ...... Log10 (n) + 1.The result is 406 Ms AC# Include # Include

In fact, the Fibonacci sequence of things I have learned in elementary school, but only then did not learn so clearly, now let us take a look at the Fibonacci sequence of some algorithms (beginners can see)Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 2

The page number of a book is encoded from the natural number 1 in order until the natural number N. The pages of the book are arranged in the usual way, with no extra leading digits of 0 per page. For example, page 6th is represented by 6 instead of

Topic Links:http://poj.org/problem?id=1423http://acm.hdu.edu.cn/showproblem.php?pid=1018Main topic:Ask n! how many bits there are. 1Ideas:N is a large scale. You cannot directly simulate the number of digits to be evaluated. Consider this approach

This idea can be understood through 2.2.1:First, let's look at the nature of the logarithm. Loga (B ^ c) = C * Loga (B), Loga (B * C) = Loga (B) + Loga (C );Assume that a number of 10234432 is given, then log10 (10234432) = log10 (1.0234432*10 ^ 7) =

The Stirling formula is a mathematical formula used to approximate the n factorial. In general, when N is very large, the calculation of n factorial is very large, so the Stirling formula is very useful, and even when N is very small, the Stirling

The solve function in MATLAB is mainly used to solve the analytic solution or exact solution of the linear equation Group. For the resulting result is a symbolic variable, the numerical solution of any number of digits can be obtained by VPA
