I was bored so I wrote a modulo operator in C++. When I enter 17 and 2 (17 % 2), it returns 7 instead of 1. What did I do wrong? #include <iostream> #include "Header.h" double modulo(double number1, double number2) { int counter=0; double result1=0; double result2 = 0; while (number1 / number2 > result1) ..

to practice C++ i decided to write a modulo function. but it returns -nan(ind) how can i make it that the return is the rest of the division? #include <iostream> #include "Header.h" double modulo(double number1, double number2) { double intermediate_result_1=5; double result; int counter = 0; while (intermediate_result_1 < number1) { counter++; intermediate_result_1 = number2 ..

What method of exponentiation modulo is used in RSA? I need this to verify 2048bit digital signatures. I am implementing it in c ++. https://en.wikipedia.org/wiki/Modular_exponentiation Source: Windows Que..

Question – You are given two positive integers a and b. In one move you can increase a by 1 (replace a with a+1). Your task is to find the minimum number of moves you need to do in order to make a divisible by b. It is possible, that you have to make 0 ..

I want to implement 5%3=2 by avx. normal: int64 x = a % b math: int64 x = a-((double)a/b)*b avx: __m256 tmp1 = _mm256_cvtepi32_ps(data); I need convert a big number from int64 to float, then float overflow. how to solve overflow when convert int64 to float? Source: Windows Que..

My code is working fine for small input but for say n=50, its printing wrong answer. For n=50, its printing 70436 instead of printing 265470434. Help me debug the code. Also, I think the issue can be with modulo operatiion. #include <iostream> #include <bits/stdc++.h> using namespace std; #define ll long long #define mod 1000000007 ll ..

This piece of educational code tries to return the count of dollars, quarters, dimes, nickels and pennies in a user entered integer value. When run, the program crashes and I can’t fix it. Most possibly it is a zero division that causes the crash. Any help is much appreciated. #include <iostream> using namespace std; int ..

This is my code: I have used try-catch to handle errors. Its showing timelimit exceeded. How can I optimize my solution. I have used nested loops. #include <bits/stdc++.h> using namespace std; int main() { try{ const long M = 1000000007; int T; long m,p; long long n,a,c,mm,pp,i=0,j=0; cin>>T; while(T>0){ cin>>n>>m>>p>>a>>c; long long exp=0; mm=m; long ..

So , from what i have read on the internet , modulo can do this: (a*b) % n = (a % n * b % n)%n; Which i understand because a%n * b%n can be bigger than n , so we have to take modulo n again.But i don’t get n! mod p.Algorithm from internet: ..

I am trying to find the correct amount of area of a pizza that each person will given a certain number of guests. In the code I have now, it correctly gives me the amount of each type of pizza I will need, as well as the total area in square inches of the pizzas. ..
