JavaScript Math pow() Method
The Math.pow() method is used to power a number i.e., the value of the number raised to some exponent. Since Math.pow() is a static method of Math and therefore it is always used as Math.pow() and not as a method of an object created in Math class.
Syntax:
Math.pow(base, exponent)
Parameters:
- base: It is the base number that is to be raised.
- exponent: It is the value used to raise the base.
Return Value: The Math.pow() method returns a number representing the given base raised to the power of the given exponent.
Example:
javascript
<script type="text/javascript"> console.log(Math.pow(3, 4));</script> |
Output:
81
More codes for the above method are as follows:
Program 1: When both base and exponent are passed as positive numbers in parameters:
javascript
<script type="text/javascript"> console.log(Math.pow(9, 3));</script> |
Output:
729
Program 2: When the base value is negative and the exponent is positive:
javascript
<script type="text/javascript"> console.log(Math.pow(-9, 3));</script> |
Output:
-729
Program 3: When the base value is positive and the exponent is negative:
javascript
<script type="text/javascript"> console.log(Math.pow(9, -3));</script> |
Output:
0.0013717421124828533
Program 4: When the base value is negative and the exponent has decimal point: It returns NaN.
