JavaScript Math cbrt()

cbrt() Syntax

The syntax of the Math.cbrt() method is:

Math.cbrt(number)

Here, cbrt() is a static method. Hence, we are accessing the method using the class name, Math.

cbrt() Parameter

The cbrt() method takes a single parameter:

• number - value whose cube root is to be calculated

cbrt() Return Value

The cbrt() method returns:

• the cube root of a given number
• NaN (Not a Number) if the argument is non-numeric

Example 1: JavaScript Math.cbrt()

Here, we have used the Math.cbrt() method to compute the cube root of an integer value, 27 and a decimal value, 64.144.

Example 2: cbrt() with Numeric String

In the above example, the Math.cbrt() method converts the numeric string "125" into a number and then computes its cube root.

Example 3: Cube Root of String Argument

In the above example, we have tried to calculate the cube root of the string "Harry". That's why we get NaN as the output.
