# How to Round a Number to Decimal Points in NodeJS

How do you round a number to a specific decimal point using Node.js?
Node.js has a built-in method called `toFixed()` that formats a number using fixed-point notation. The `toFixed()` method takes one number parameter that tells it how many digits to appear after the decimal point. This number can be a value between `0` and `20`.
And the method will return a `string` value representing the new number generated using fixed-point notation.
Here's an example:
Node.js

const number = 42.235888

const newNumber = number.toFixed(2)
// newNumber = 42.24
Notice that the `.toFixed(2)` method transforms the `42.235888` number to a new version with only 2 decimal points.
What happens if you applied the decimal point to a whole number?
Here's a code example for that:
Node.js

const number = 42

const newNumber = number.toFixed(3)
// newNumber = 42.000
Notice how the new number created by the `.toFixed(3)` method has three digits behind the decimal point even though they're zero.
Pretty cool, right?
Let's go over one more example where we want to transform a number with decimal points to a rounded whole number.
Here's the code:
Node.js

const number = 42.68231

const newNumber = number.toFixed(0)
// newNumber = 43
if you give a value of `0` to the `.toFixed()` method, it will round the new number to a whole number.
