The remainder / modulus operator ( % ) returns the remainder after (integer) division. This operator returns the remainder left over when one operand is divided by a second operand. When the first operand is a negative value, the return value will always be negative, and vice versa for positive values.

## How do you use a remainder operator?

The % operator returns the remainder of two numbers. For instance 10 % 3 is 1 because 10 divided by 3 leaves a remainder of 1. You can use % just as you might use any other more common operator like + or – . Perhaps surprisingly the remainder operator can be used **with floating point values as** well.

## What is reminder in JavaScript?

**Modulus %** of a division

We can get modulus of a any two numbers in JavaScript by using % . This gives us the reminder after a division. For example let us find out modulus of 23 and 5.

## How do you use modulus in JavaScript?

The JavaScript modulo operator returns the remainder of a division sum. To calculate the remainder of a division sum, use the **percentage sign (%)**. The syntax for the modulo operator is: (number_one % number_two).

## Can modulus operator be used with float?

Yes, %(modulo) **operator isn’t work with floats and double**.. if you want to do the modulo operation on large number you can check long long int(64bits) might this help you. … If you want to use an int use long long, don’t use a format that is non-ideal for your problem if a better format exists.

## How do you find the remainder?

Once you have the answer in decimal form, **subtract the whole number, then multiply the decimal value that’s left by the divisor of your original problem**. The result is your remainder. For example, divide 346 by 7 to arrive at 49.428571.

## What are three dots in JavaScript?

The three dots in JavaScript are **the spread / rest operator**. The spread syntax allows an expression to be expanded in places where multiple arguments are expected. The rest parameter syntax is used for functions with a variable number of arguments. The spread / rest operator for arrays was introduced in ES6.

## What is the main purpose of JavaScript?

JavaScript is a text-based programming language used both on the client-side and server-side that **allows you to make web pages interactive**. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user.

## What does %= mean in JavaScript?

%= Get **the modulus of left operand divide by right operand** and assign resulted modulus to the left operand. Example: Assignment operators.

## What is the operator in JavaScript?

An operator is **capable of manipulating a certain value or operand**. Operators are used to perform specific mathematical and logical computations on operands. In other words, we can say that an operator operates the operands. In JavaScript operators are used for compare values, perform arithmetic operations etc.

## How do you check if a number is a multiple of another JavaScript?

Use **the % (modulus) operator** in Javascript and PHP, which returns the remainder when a is divided by b in a % b . The remainder will be zero when a is a multiple of b . Ex. You can use the modulus to find the remainder after a division and then if the remainder is equal to zero then it’s a multiple.

## How do you make a calculator in JavaScript?

**Example 1: Create a JavaScript Calculator using the JavaScript, HTML and CSS programming languages.**
