⚠ Если будет передано функции 24, то на выходе получим 24,00 рублей.
Чтобы рассчитать правильное окончание, нужно учесть также остаток от деления на 10. Остаток от 100 стоит проверять в диапазоне чисел от 11 до 19 включительно
Также рекомендую сначала округлить число
double lastNumber = (int) Math.floor(num);
А затем получить остаток
lastNumber % 100; и lastNumber % 10;
