Difficulty with formatting decimal points in JavaScript

Difficulty with formatting decimal points in JavaScript

I seem to be having an issue with decimal places in my code. Currently, it's showing the result as 123 123 12 but I actually need it to be displayed as 12 312 312.

Is there anyone who can assist me with formatting this correctly?

Here is the section of code:

        var fcqInteger = parseInt(fcq.replace(/\s/g, ''));
        valPrice = parseFloat(valPrice.replace(',', '.'));
        var marketCap = (fcqInteger * valPrice)+'';
        // result
        var marketCapParts = marketCap.match(/[\s\S]{1,3}/g) || []; 
        marketCap = marketCapParts.join(' ');

Thank you for any assistance provided.

To easily replace spaces, search for groups of three at the end of the string.

var data = '12312312'

console.log(data.replace(/.{1,3}(?=(...)+$)/g, '$& '));  // replace
console.log(data.match(/.{1,3}(?=(...)*$)/g).join(' ')); // match/join

To make your number more readable, you can utilize the Number.toLocaleString method and then substitute any commas with spaces.

let number = '123 123 12';
let result = Number(number.replace(/\s/g, '')).toLocaleString('us-US', {maximumFractionDigits: 5}).replace(/,/g, ' ');
console.log(result)
