Creating from floats

Dinero objects must be instantiated with integers, in minor currency units. For example, to create an object for $19.99, you should write the following code:

import { dinero, add, subtract } from 'dinero.js';
import { USD } from '@dinero.js/currencies';

const d = dinero({ amount: 1999, currency: USD });

If you have amounts as floats (in this case, 19.99) and you want to abstract object creation, you can write your own helper.

function dineroFromFloat({ amount: float, currency, scale }) {
  const factor = currency.base ** (currency.exponent || scale);
  const amount = Math.round(float * factor);

  return dinero({ amount, currency, scale });
}
