I'm calculating my totals and then i want them to be fixed to 2 decimal places.Check my code below.

this.selectedCompaniesDetails.forEach((company)=>{
                            if(company.id == p.company_id)
                            {
                                if (!tot[p.company_id])
                                {   tot[p.company_id] = [] }
                                    const numberPrice = parseFloat(p.price)
                                
                                 tot[p.company_id].push(numberPrice)
                            }
                        });

The parseFloat(p.price) function is giving me weird answers. Check my screen shot below.

Try something like this,

let num = 5.56789;
let n = num.toFixed(2);

console.log(num);
console.log(n);

CodePudding user response：

use Math.round(num "e 2") "e-2"

function roundToTwo(num) {
   return  (Math.round(num   "e 2")    "e-2");
}

let number = 139.605;
let round = roundToTwo(number)
var f = number .toFixed(2);

console.log('original', number);
console.log('expected', 139.61);
console.log('(Correct)round', round);
console.log('(Wrong)toFixed', f);
