  percent_vat: 11, 
  total_price: 1650000,
  total_dpp: 1486486.1, 
  total_discount: 148648.5, 
  total_vat: 147162.4 
}

Or you want to rounding the number?

import { numberRounding } from 'duopomelo-ppn-calculator';
//const { numberRounding } = require('duopomelo-ppn-calculator'); // legacy way

const theNumber = numberRounding(3.1415926535897, 3);
console.log(theFinalPrice); // output: 3.142
