javascript
Parameters: number n (float)
The number to calculate the cube root of
Returns: Cube root of the input number (float)
The findCubeRoot function is used to calculate the cube root of a given number. It makes use of the in-built Math.cbrt() function in JavaScript.
Hello fellow programmer! This post will guide you through the process of creating a JavaScript function named 'findCubeRoot'. This function will take one input: a number, and it will return the cube root of said number. The function will use JavaScript's built-in Math object. Beyond the function creation, you'll also be shown how to call this function, passing in a number as an argument. Relax, take your time & enjoy the journey of coding.
Before we start coding, let's have a basic understanding of what we need to do. The task requires us to write a function in JavaScript that will calculate the cube root of a given number.
We start by defining the function. We'll call the function findCubeRoot
, and it will accept one parameter, which is the number we want to find the cube root of.
So, our function looks like this:
function findCubeRoot(num) {
}
In JavaScript, the Math.cbrt()
method is used to find the cube root of a number. We can use this method inside our function to get the cube root of the number passed to it.
Here is how it looks:
function findCubeRoot(num) {
return Math.cbrt(num);
}
Now our function is ready, it's time to test it. We need to call our function with a number for which we want to find the cube root.
This is how the call to the function will look like:
console.log(findCubeRoot(8)); // Output: 2
The function correctly returns 2, which is the cube root of 8.
The full code for our findCubeRoot
function is shown below:
function findCubeRoot(num) {
return Math.cbrt(num);
}
console.log(findCubeRoot(8)); // Output: 2
As seen above, we've successfully created the findCubeRoot
function in JavaScript. This function takes a number as an argument and returns its cube root. Thanks to JavaScript's built-in Math.cbrt()
method, our function is concise and efficient.
The cube root of a number is a value that, when cubed, gives the original number. For example, the cube root of `8` is `2` because `2*2*2 = 8`. In JavaScript, this is achieved using the `Math.cbrt(number)` function.
