Jul 8, 2013 · The modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, the latter being called the modulus of the operation. (source: wikipedia)

In an Introduction to Abstract Algebra by Thomas Whitelaw, he gives examples of the congruence mod operation, such as $13 \\equiv5 \\pmod4$, and $9 \\equiv -1 \\pmod 5$. But when I first learned about...

I have attached an image showing a Modulo 2 binary division. I can roughly understand the working below which is using XOR calculation but I am not sure how the answer (in red) is being computed ...

Let's say that I need to format the output of an array to display a fixed number of elements per line. How do I go about doing that using modulo operation? Using C++, the code below works for displ...

May 16, 2015 · 16 I really can't get my head around this "modulo" thing. Can someone show me a general step-by-step procedure on how I would be able to find out the 5 modulo 10, or 10 modulo 5. …

Apr 9, 2017 · The modulo operator in C will give the remainder that is left over when one number is divided by another. For example, 23 % 4 will result in 3 since 23 is not evenly divisible by 4, and a …

4 I am primarily a programmer (rather than a mathematician) and have recently come across a coding problem where I must invert a function which is the the modulo of a multiplication (given certain …

I can write the program int a = 3; int b = 4; Console.WriteLine(a % b); The answer I get is 3. How does 3 mod 4 = 3??? I can't figure out how this is getting computed this way.

For example: $$7x \\equiv 1 \\pmod{31} $$ In this example, the modular inverse of $7$ with respect to $31$ is $9$. How can we find out that $9$? What are the steps that I need to do? Update If I have a

Oct 23, 2010 · 10 The simplest general function to find the positive modulo would be this- It would work on both positive and negative values of x.
