将字符串转换为数字但在 Javascript 中保留零

Question

I am working with GBP currency in Javascript and converting a string currency to a number like the following: Number('1.20') will give me 1.2 . But I want to maintain the 0 when converting to a number type. Is this possible? This is the result that I want: 1.20 . Can anyone help me please?

Answer 1

A better way to work with Currency in Javascript is to use the Intl.NumberFormat . For course, the output will be of the type: 'String'

The output will take care of the number of decimal places depending on the Currency you specify. In your case GBP so it will be 2 decimal places.

Example:

 const number = 1.2; console.log(new Intl.NumberFormat('en', { style: 'currency', currency: 'GBP' }).format(number));

Answer 2

You can control the decimals like this in Javascript:

let num = 1.204;
let n = num.toFixed(2)
