Sometimes, we want to parse numbers with comma decimal separators in JavaScript.
In this article, we’ll look at how to parse numbers with comma decimal separators in JavaScript.
How to parse numbers with comma decimal separators in JavaScript?
To parse numbers with comma decimal separators in JavaScript, we can remove all the comma separators with the JavaScript string’s replace method.
Then we can use Number to parse the number.
For instance, we write:
const n = '123,456.789'
const num = n.replace(/,/g, '');
const parsed = Number(num)
console.log(parsed)
to call n.replace to replace all the commas with empty strings.
Then we call Number with num to convert num to a number.
As a result, parsed is 123456.789.
Conclusion
To parse numbers with comma decimal separators in JavaScript, we can remove all the comma separators with the JavaScript string’s replace method.
Then we can use Number to parse the number.
