Basic Conversion

import { ToWords } from 'to-words';

const tw = new ToWords({ localeCode: 'ru-RU' });
tw.convert(12345);
// "Двенадцать Тысяч Триста Сорок Пять"

tw.convert(1234.56, { currency: true });
// "Одна Тысяча Двести Тридцать Четыре Рубля Пятьдесят Шесть Копеек"

Gender

tw.convert(1, { gender: 'masculine' }); // "Один"
tw.convert(1, { gender: 'feminine' }); // "Одна"

Fraction Style

tw.convert(0.21, { decimalStyle: 'fraction' });
tw.convert(1.21, { decimalStyle: 'fraction' });

Russian applies Slavic-specific plural logic when fraction-style decimal wording is enabled. Currency mode continues to emit Ruble and Kopeck unit names.
