Today, we will discuss **Math.round to 2 Decimal Places in JavaScript**. If you want to learn new insights, read on!

In this article, you’ll discover how to round numbers to 2 decimal places in JavaScript using the Math.round() method, the toFixed() method, and a custom rounding function.

This tutorial is ideal for those dealing with financial calculations or situations where precision is critical.

**How to round a number to 2 decimal places in JavaScript using Math.round? **

Using **Math.round()** method you can round a number to 2 decimal places. Mainly, because this method rounds a number to the nearest integer.

**Here’s the syntax of Math.round:**

**Math.round(x)** ✅

To round to two decimal places, you can multiply the number by 100 (or a power of 10 corresponding to the number of decimal places you want), round it to the nearest whole number, and then divide it by 100.

**Here’s an example code:**

**// Define the number
var sampleNumber = 143.356;
// Round the number to 2 decimal places
var sampleRoundedNum = Math.round(sampleNumber * 100) / 100; ✅
// Display the result
console.log(sampleRoundedNum);
**

**Output:**

**143.36**

**Additional solutions to round a number to 2 decimal places in JavaScript**

Apart from using **Math.round()**, there are other methods that you can use to round a number to 2 decimal places in JavaScript

**Use the toFixed() method**

The** toFixed()** method is one of the best way to round a number to two decimal places in JavaScript.

Here’s the syntax of **toFixed() **method:

**num.toFixed([decimal digits])** ✅

**Here’s an example code:**

**var sampleNumber = 567.789;
var sampleRoundedNum = sampleNumber.toFixed(2);;✅
console.log(sampleRoundedNum);
**

**Output:**

**567.79**

**Creating a custom function for rounding**

This function uses exponential notation to first shift the decimal point in the number n places to the right (via “e+n”), rounds the result to the nearest integer, and then shifts the decimal point n places back to the left (via “e-n”).

**Here’s the syntax:**

**function roundToTwo(num) { ****✅**
return +(Math.round(num + "e+2") + "e-2");
}

**Here’s an example code:**

**function roundToTwo(num) { ✅
return +(Math.round(num + "e+2") + "e-2");
}
var SampleNumber = 567.789;
var SampleroundedNumber = roundToTwo(SampleNumber);
console.log(SampleroundedNumber);
**

**Output:**

**567.79**

📌Please note that JavaScript’s handling of floating-point arithmetic might lead to unexpected results in some cases due to precision errors.

If you’re dealing with financial calculations or other situations where precision is critical, consider using a library designed for precise decimal arithmetic.

**Conclusion**

In conclusion, we have explored **how to round a number to 2 decimal places in JavaScript** using several methods.

The Math.round() method and the toFixed() method are built-in JavaScript functions that make this task straightforward.

Also, we added creating a custom rounding function that is more flexible and has control over the rounding process.

We hope this article has provided you with enough information to understand the** Math.round to 2 decimal places JavaScript**.
