# What is the use of modulus operator in JavaScript?

Contents

The JavaScript modulo operator calculates the remainder left over after dividing two numbers. It is commonly used with an if statement to evaluate whether a number is odd or even. The modulo operator is represented by a percentage sign.

## What is the purpose of using modulus operator?

The modulus operator – or more precisely, the modulo operation – is a way to determine the remainder of a division operation. Instead of returning the result of the division, the modulo operation returns the whole number remainder.

## Where is MOD operator used?

The modulus operator returns the remainder of a division of one number by another. In most programming languages, modulo is indicated with a percent sign. For example, “4 mod 2″ or “4%2” returns 0, because 2 divides into 4 perfectly, without a remainder.

## What is the modulus (%) operator used for?

The modulo operator, denoted by %, is an arithmetic operator. The modulo division operator produces the remainder of an integer division. produces the remainder when x is divided by y.

## How do you use modulus operator?

The modulo operator provides the whole number left after dividing the first number by the second number. This means that subtracting the remainder from the first number will make it a multiple of the second number. For example, 28 can be changed to be a multiple of 5 by taking the modulo 28 % 5.

## What modulus means?

1a : the factor by which a logarithm of a number to one base is multiplied to obtain the logarithm of the number to a new base. b : absolute value sense 2.

## How does modulus work?

The modulus operator, sometimes also called the remainder operator or integer remainder operator works on integers (and integer expressions) and yields the remainder when the first operand is divided by the second. In Python, the modulus operator is a percent sign ( % ). The syntax is the same as for other operators.

## What does a ≡ b mod n mean?

Definition 3.1 If a and b are integers and n > 0, we write a ≡ b mod n to mean n|(b − a). We read this as “a is congruent to b modulo (or mod) n. For example, 29 ≡ 8 mod 7, and 60 ≡ 0 mod 15. The notation is used because the properties of congruence “≡” are very similar to the properties of equality “=”.

## What is the mod symbol?

Modulo is a math operation that finds the remainder when one integer is divided by another. In writing, it is frequently abbreviated as mod, or represented by the symbol %.

## What does mod 8 mean?

1 mod 8 is short for 1 modulo 8 and it can also be called 1 modulus 8. Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask “What is 1 mod 8?” you are asking “What is the Remainder when you divide 1 by 8?”.

## What is the difference between modulus and remainder?

Remainder is simply the remaining part after the arithmetic division between two integer number whereas Modulus is the sum of remainder and divisor when they are oppositely signed and remaining part after the arithmetic division when remainder and divisor both are of same sign.

## Which is a logical operator?

A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.

## What does mod 7 mean?

1 mod 7 is short for 1 modulo 7 and it can also be called 1 modulus 7. Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask “What is 1 mod 7?” you are asking “What is the Remainder when you divide 1 by 7?”.

## Can we use modulus operator in 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 calculate modulus?

How to calculate the modulo – an example

1. Start by choosing the initial number (before performing the modulo operation). …
2. Choose the divisor. …
3. Divide one number by the other, rounding down: 250 / 24 = 10 . …
4. Multiply the divisor by the quotient. …
5. Subtract this number from your initial number (dividend).

## What is modulus number?

The modulus of a number is its absolute size. That is, we disregard any sign it might have. Example The modulus of −8 is simply 8. … So, the modulus of a positive number is simply the number. The modulus of a negative number is found by ignoring the minus sign.
