  converterOptions: {
    currency: true,
    ignoreDecimal: false,
    ignoreZeroCurrency: false,
    doNotAddOnly: false,
  }
});

Options can be set at instance level, or along with individual call to convert method.

const toWords = new ToWords();

let words = toWords.convert(123);
// words = One Hundred Twenty Three

words = toWords.convert(123.45);
// words = One Hundred Twenty Three Point Fourty Five

words = toWords.convert(123.045);
// words = One Hundred Twenty Three Point Zero Four Five

Note: When fractional part starts with zero, the digits after decimal points are converted into respective numbers individually

To convert to currency

const toWords = new ToWords();

let words = toWords.convert(452, { currency: true });
// words = Four Hundred Fifty Two Rupees Only

words = toWords.convert(452.36, { currency: true });

const toWords = new ToWords();

let words = toWords.convert(452.36, { currency: true, ignoreDecimal: true });
// words = Four Hundred Fifty Two Rupees Only
