JavaScript Math.pow()
Syntax & Examples
Math.pow() static-method
The Math.pow() method in JavaScript returns the base to the exponent power, that is, base raised to the power of exponent (base^exponent). It is a static method of Math, meaning it is always used as Math.pow() and not as a method of a Math object created (Math is not a constructor).
Syntax of Math.pow()
The syntax of Math.pow() static-method is:
Math.pow(base, exponent)This pow() static-method of Math returns base x to the exponent power y (that is, x^y).
Parameters
| Parameter | Optional/Required | Description |
|---|---|---|
base | required | The base number. |
exponent | required | The exponent used to raise the base. |
Return Type
Math.pow() returns value of type Number.
✐ Examples
1 Using Math.pow() with positive base and exponent
In this example, we use the Math.pow() method to calculate 2 raised to the power of 3.
For example,
- We call
Math.pow()with 2 and 3 as the arguments. - The method returns 2 raised to the power of 3.
- We log the result to the console using
console.log().
JavaScript Program
console.log(Math.pow(2, 3));Output
8
2 Using Math.pow() with a negative base
In this example, we use the Math.pow() method to calculate -2 raised to the power of 3.
For example,
- We call
Math.pow()with -2 and 3 as the arguments. - The method returns -2 raised to the power of 3.
- We log the result to the console using
console.log().
JavaScript Program
console.log(Math.pow(-2, 3));Output
-8
3 Using Math.pow() with a negative exponent
In this example, we use the Math.pow() method to calculate 2 raised to the power of -3.
For example,
- We call
Math.pow()with 2 and -3 as the arguments. - The method returns 2 raised to the power of -3.
- We log the result to the console using
console.log().
JavaScript Program
console.log(Math.pow(2, -3));Output
0.125
