Basic Conversion

import { ToWords } from 'to-words';

const tw = new ToWords({ localeCode: 'it-IT' });

tw.convert(10); // "Dieci"
tw.convert(100); // "Cento"
tw.convert(1000);
tw.convert(1000000);

Italian uses the European long-scale sequence with words such as Miliardo and Bilione, which matters when your product handles very large values.

tw.convert(1234.56, { currency: true });
tw.convert('500.00', { currency: true, includeZeroFractional: true });
