How to Format a Number to 2 Decimal Places in JavaScript
February 9, 2024
In JavaScript, formatting numbers to two decimal places is a common requirement for displaying numerical data, especially when dealing with currencies or precise measurements. There are a couple of ways to do this. We’ll cover them in this article.
How to use thetoFixed
method to format a number to 2 decimal places?
The toFixed
method converts a number into a string, rounding to a specified number of decimal places. It's the most straightforward way to format a number to two decimal places.
const number = 123.456; const formattedNumber = number.toFixed(2); console.log(formattedNumber); // Output: "123.46"
You could ship faster.

How to use thetoLocaleString
method in formatting numbers to 2 decimal places?
For more control over formatting, including localization options, use thetoLocaleString
. This method lets you specify the number of decimal places while considering the local numbering system.
const number = 123.456; const formattedNumber = number.toLocaleString('en-US', { minimumFractionDigits: 2, maximumFractionDigits: 2 }); console.log(formattedNumber); // Output: "123.46"
Rounding using Math functions
In some cases, you might want to perform rounding operations before formatting. This approach gives you control over how rounding is handled (e.g., Math.round
, Math.ceil
, Math.floor
).
const number = 123.456; const roundedNumber = Math.round(number * 100) / 100; console.log(roundedNumber.toFixed(2)); // Output: "123.46"
Selecting the right method depends on your specific needs—toFixed
for simple rounding and conversion to a string, toLocaleString
for localized formatting, and math functions for more control over rounding. JavaScript's flexibility allows for precise and readable numeric presentations.
