I am trying to implement a map / function which has the equation Bernoulli Shift Map x_n+1 = 2* x_n mod 1 The output of this map will be a binary number which will be either 0/1. So, I generated the first sample x_1 using rand. The following is the...

Hello everyone I was having some issue splitting up a user input number using printf (I do have to use printf). My problem is that when I put in say the number 12345 it will print the integers on five separate lines, and also has them in the reverse order....

Can someone please explain the under-the-hood mechanics of x % y !=0 in C++? It evaluates to 0 if there is no remainder in integer division and it evaluates to 1 if there is any remainder of any amount. I find this to be quite useful, but I'd like to...

Suppose I have two long longs, a and b, that I need to multiply, then get the value mod k for some large k, such that a, b, and k are all in the range of long long but not of int. For simplicity, a, b < k. Thus the...

The IDEA cipher uses multiplication modulo 2^16 + 1. Is there an algorithm to perform this operation without general modulo operator (only modulo 2^16 (truncation))? In the context of IDEA, zero is interpreted as 2^16 (it means zero isn't an argument of our multiplication and it cannot be the result,...

Hey guys so I am wondering if this is possible. So in my game I have it set up to where if they make a point the score goes up by 5. I implemented a multiplier in the game so if they dont get hit and continue making points then...

If we are told that we can't use modulus operator then how can we take out the last digit of a number. e.g. N=2345, we should get 5. Try to provide a generic solution. What I found: N- N/ 10 * 10 ...

I have written this code in C where each of a,b,cc,ma,mb,mcc,N,k are int . But as per specification of the problem , N and k could be as big as 10^9 . 10^9 can be stored within a int variable in my machine. But internal and final value of of...

Suppose I have a integer array containing digits and I want to take modulus of value stored in it, i.e int a[36]={1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9} and convert it into a number like 987654321987654321987654321987654321. In C language long long int permits only 10^18. I want to take modulus with 10^9+7. How can i do...

I am learning this algorithm to calculate nth number in fibonacci series. This is my code, #include <bits/stdc++.h> using namespace std; #define MOD 1000000007 long long int fib(long long int n) { if(n < 2) return n; if(n == 2) return 1; long long int k = n/2; long long...

I have the following number; let's call it number one -1757151608 then I have a second number, let's call it unknown 94507795 and finally, I have the product, let's call it number two -1000 If I multiply the first two numbers in form, I get the answer as -1000. Problem...

I am very new to C++ and am attempting create a function to implement the Euclidean algorithm that returns the greatest common divisor for two integer inputs. The current approach I am taking keeps crashing - can you help me understand why? int main() { int a = 0; int...

This is an incredibly specific question, as i simply need to know if this pattern has a name and if there is a more effective way of doing it. (disregard the obvious declaration in the for loop) for (int i = 0; i < 8; i++) { int mod =...

I have journal articles which contain three issues per volume. Is there a formula to increment 1.1, 1.2, 1.3 and then jump to 2.1, 2.2, 2.3?...

I've created a DataSet in ASP.NET and replaced the default Fill query with the following SQL statement: SELECT Resolved_Request.ResolvedReqID, In_Progress_Request.DateAssigned, Resolved_Request.DateResolved, Fix(((DATEDIFF('n', In_Progress_Request.DateAssigned, Resolved_Request.DateResolved) / 60 / 24))) & ' days, ' & ((DATEDIFF('n', In_Progress_Request.DateAssigned, Resolved_Request.DateResolved) / 60) Mod 24) & ' hours and ' & (DATEDIFF('n', In_Progress_Request.DateAssigned, Resolved_Request.DateResolved) Mod...

688^79 mod 3337 = 1570. When I tried this at wolfram alpha I got: but When I entered the same thing in Matlab, I get 364 as the answer. I got to be doing something wrong. Any light on this will be appreciated....

I remember from assembly that integer division instructions yield both the quotient and remainder. So, in python will the built-in divmod() function be better performance-wise than using the % and // operators (suppose of course one needs both the quotient and the remainder)? q, r = divmod(n, d) q, r...

I have a simple for loop: for index, (key, value) in enumerate(self.addArgs["khzObj"].nodes.items()): and I want to start a new wx horizontal boxsizer after every 3rd item to create a panel with 3 nodes each and going on for as many as are in nodes. The obvious solution is to do:...

I am writing a program in assembly to calculate the modulus of a number. I do not need help with the the program, but I do need help understanding how modulo works with negative numbers. I have researched stackoverflow but I seem to be finding conflicting results. Also, I would...

At least in MySQL v5.1.73 (CentOS 6.6), MOD() function returns a bogus result... unless someone can explain how this is actually correct. mysql> select MOD(-385.4784399 ,1440); +-------------------------+ | MOD(-385.4784399 ,1440) | +-------------------------+ | -385.4784399 | +-------------------------+ 1 row in set (0.01 sec) Is this the best alternative? mysql> select -385.478439885319...

Given three numbers N, A and B. Find how integers in range from 1 to N are divisible by A or B. I can't use modulus operator from range 1 to N because N can be as large as 10^12 and then I would run out of allocated time for...

How can I write a modulus that will select the following iterations in sequence? 1, 4, 5, 8, 9, 12, 13 etc (+3+1r) I'm working within a loop and counting posts (iterations). So for example, I could catch every third post (1, 4, 7, 10) by:- if ($i % 3...
