Angular2 modulus functionality to create rows of elements

I am having trouble recreating and imagining how to recreate the following piece of vanilla Javascript code in Angular2 (I just typed it out on the spot so don't worry about syntax or logic errors). As you can see, I am looping through an array of…

Javascript's Modulus broken?

I just found out that when you type Math.pow(5,25) % 5 in the console, it returns 2. This also happens when you first solve Math.pow(5,25) (298023223876953150 % 5 = 2). But that number is clearly divisible by 5, because it is a power of 5... Has…

Big Integer Modular Exponentiation

How to calculate (xy) mod z with 1 <= x, y <= 101000 and z any positive integer 1 <= z < 231 ? What I have done so far is: scan x and y as a string, get the modulo, then calculate (xy) mod z. I know this is wrong because (xy) mod z is not equal to…

Modulus formula

I'm reading a C++ Primer 5th ed and i don't understand why is this true : The modulus operator is defined so that if m and n are integers and n is nonzero, then (m/n)*n + m%n is equal to m. I decided to check this and the result was indeed…

Is there a way to optimize reducing many numbers to the same modulus

I am writing a program to do integer factorization and have to reduce a series of numbers to a given modulus. Both the number and the modulus are bigints, say 50 to 100 digits. The number changes but the modulus is always the same. Is there some…

Rabin Karp algorithm for big strings

I wrote a simple step-by-step implementation of Rabin-Karp algorithm for substring search, and it seems to work fine until the hash becomes greater than the modulus, and then it goes wrong... Here is the code, it's quite simple: typedef long long…

Is there something happening when string formatting that uses the modulus function while calling either StringOperand % TupleOperand or StringOperand % DictionaryOperand Or is it just an arbitrary use of % for the string formatting function? I'm…

what does num%2 mean in java?

this is the code fragment. I'm not too sure what num%2 is though. % would give the remainder, so does that mean that the remainder of num must be 2? int num = 1, max = 20; while (num < max) { if (num%2 == 0) System.out.println(num); …

Java integer max test with clockwork modulus statement returning incorrect value

In class we're currently working with a "clockwise" modulus function - that is to say, a function which essentially works the same as Math.floorMod(int a, int b). For class, I cannot use Math.floorMod(), and I have written this after researching…
