JavaScript Math.imul()
Syntax & Examples

Math.imul() static-method

The Math.imul() method in JavaScript performs a 32-bit integer multiplication of two numbers. This method is useful for tasks that require high-performance integer arithmetic. It is a static method of Math, meaning it is always used as Math.imul() and not as a method of a Math object created (Math is not a constructor).

Syntax of Math.imul()

The syntax of Math.imul() static-method is:

Math.imul(a, b)

This imul() static-method of Math returns the result of the 32-bit integer multiplication of x and y.

Parameters

ParameterOptional/RequiredDescription
arequiredThe first number to multiply.
brequiredThe second number to multiply.

Return Type

Math.imul() returns value of type Number.


✐ Examples

1 Using Math.imul() with positive integers

In this example, we use the Math.imul() method to multiply two positive integers, 2 and 3.

For example,

  1. We call Math.imul() with 2 and 3 as the arguments.
  2. The method returns the 32-bit integer multiplication of 2 and 3.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.imul(2, 3));

Output

6

2 Using Math.imul() with a positive and a negative integer

In this example, we use the Math.imul() method to multiply a positive integer, 2, and a negative integer, -3.

For example,

  1. We call Math.imul() with 2 and -3 as the arguments.
  2. The method returns the 32-bit integer multiplication of 2 and -3.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.imul(2, -3));

Output

-6

3 Using Math.imul() with large numbers

In this example, we use the Math.imul() method to multiply two large numbers, 123456 and 789012.

For example,

  1. We call Math.imul() with 123456 and 789012 as the arguments.
  2. The method returns the 32-bit integer multiplication of 123456 and 789012.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.imul(123456, 789012));

Output

1942908512
