Script Preparation code:

const decimalPlaces = 14;

function toFixed(n) {
    return Math.round(n * Math.pow(10, decimalPlaces)) / Math.pow(10, decimalPlaces);
}

function add(a, b) {
    return toFixed(a + b);
}

function subtract(a, b) {
    return toFixed(a - b);
}

Tests:

Native
var a = 0.1; var b = 0.2; ((a + b) * b).toString();
Native + toFixed
var a = 0.1; var b = 0.2; ((a + b) * b).toFixed(9);
decimal.js
var a = new Decimal("0.1"); var b = new Decimal("0.2"); a.plus(b).times(b).toString();
big.js
var a = new Big("0.1"); var b = new Big("0.2"); a.plus(b).mul(b).toString();
bignumber.js
var a = new BigNumber("0.1"); var b = new BigNumber("0.2"); a.plus(b).multipliedBy(b).toString();
Option 1
var a = 0.1; var b = 0.2; toFixed(toFixed(a + b) * b).toString();
