JavaScript - Math.pow() Method



The JavaScript Math.pow() method returns the base raise to the power of exponent.

Syntax

Math.pow(base, exponent);

Parameters

base Specify the base.
exponent Specify the exponent.

Return Value

Returns the base raise to the power of exponent.
If the base is negative and the exponent is not an integer, the result is NaN.

Example:

In the example below, Math.pow() method is used to calculate the base raised to the power of exponent.

var txt;

txt = "Math.pow(5, 2) = " + Math.pow(5, 2) + "<br>";
txt = txt + "Math.pow(5, 2.5) = " + Math.pow(5, 2.5) + "<br>";
txt = txt + "Math.pow(5.5, 2.5) = " + Math.pow(5.5, 2.5) + "<br>";
txt = txt + "Math.pow(-5, 2) = " + Math.pow(-5, 2.) + "<br>";
txt = txt + "Math.pow(-5, 2.5) = " + Math.pow(-5, 2.5) + "<br>";
txt = txt + "Math.pow(-5.5, 2.5) = " + Math.pow(-5.5, 2.5) + "<br>";

The output (value of txt) after running above script will be:

Math.pow(5, 2) = 25
Math.pow(5, 2.5) = 55.90169943749474
Math.pow(5.5, 2.5) = 70.94253836732938
Math.pow(-5, 2) = 25
Math.pow(-5, 2.5) = NaN
Math.pow(-5.5, 2.5) = NaN
