var decimal = require("decimal.js");

Decimal.js provides over forty methods that can be used to work with numbers. You will see it in the forms we deliver that work with payments to overcome the limitations around using floating points to store currency values.

As with all payment information, totals should be calculated server-side, not in the browser.

let result = x.times(y);
return parseFloat(result); // returns 0.02
