如何将字符串转换为数字 javascript

Question

I have a string that is 11.786.775,13 and I need to convert into a number, but if I use parseInt return 11, and if I use parseFloat return 11.786, I need the 11.786.775,13 but as a number. Here my code:

let x = number.toLocaleString('pt-br', {minimumFractionDigits: 2});

Answer 1

replace the dots with an empty string and the comma with a dot and then use parseFloat

const cleanStrNumber = x.replace(/\./g, '').replace(',','.');
const num = parseFloat(cleanStrNumber, 10);

Answer 2

My solution:

let x = '11.786.775,13';
x = parseFloat(x.split('.').join('').replace(',','.'));
console.log(typeof x, x);

for x equals '11.786.775,13' or '175,13' slower (3%) than .replace(/\./g, '') ; but for x = '9.9.9.9.9.9.9.9.9.9.9.9.11.786.775,13', replace is slower than split-join construction

if you have small numbers(less 4 points), it is better to choose @tomer-almog design(replace).
