В настоящее время у нас есть грубый механизм преобразования чисел в слова (например, с использованием нескольких статических массивов) и основанный на размере числа, переводящий это в английский текст. Но мы сталкиваемся с огромными проблемами в отношении цифр.
10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight
Есть ли в какой-либо математической библиотеке простая в использовании функция, которую я могу использовать для этой цели?
Вот код, я не думаю, что в SE есть какой-либо метод.
Он в основном преобразует число в строку, анализирует строку и связывает ее с весом.
например
1000
1 рассматривается как тысяча, а 1 сопоставляется с "one" и тысячей из-за позиции

Вы можете обработать преобразование «доллар и цент», дважды вызвав метод convert.
String phrase = "12345.67" ;
Float num = new Float( phrase ) ;
int dollars = (int)Math.floor( num ) ;
int cent = (int)Math.floor( ( num - dollars ) * 100.0f ) ;
String s = "$ " + EnglishNumberToWords.convert( dollars ) + " and "
+ EnglishNumberToWords.convert( cent ) + " cents" ;

Потому что у вас не может быть общего алгоритма для каждой локали, нет. Вы должны реализовать свой собственный алгоритм для каждой поддерживаемой вами локали.
** ИЗМЕНИТЬ **
Просто, черт возьми, я играл, пока не получил этот класс. Он не может отображать Он может отображать любые числа до 66 цифр и 26 знаков после запятой используя строковое представление числа. Вы можете добавить еще Long.MIN_VALUE из-за битовых ограничений ... но я предполагаю, что его можно изменить и изменить long типы значений на double для десятичных или даже больших чиселScaleUnit для большего количества десятичных знаков ...

getName(string) - удобный способ предоставить число, которое в противном случае было бы слишком большим для передачи напрямую по значению (т. Е. С использованием double). Пример не предоставляет недопустимые выходные данные, поскольку предполагается, что значения были правильно проверены.

BigInteger и BigDecimal. Это позволило бы избежать проблемы, которую вы описываете.

Взгляните на Tradukisto. Это написанная мной библиотека Java, которая выполняет эту работу.
В этом посте я только что обновил код Яника Рошона. Я сделал его работоспособным с более ранней версией java 1.6, и я получал результат для 1,00 = одна сотая. Итак, мне нужно обновить код. Новое, я получаю результат для 1,00 = одна ноль сотых.
Я не знаю, что мне делать. Добавьте новый ответ или отредактируйте это сообщение. Поскольку ответ имеет высокий рейтинг, я сделал новый пост с обновлением кода. Я только что изменил эти две вещи, упомянутые выше.

Вы можете использовать RuleBasedNumberFormat. например результат даст вам Ninety
ULocale locale = new ULocale(Locale.US); //us english
Double d = Double.parseDouble(90);
NumberFormat formatter = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);
String result = formatter.format(d);
Он поддерживает широкий спектр языков.
Вы можете использовать ICU4J, просто нужно добавить запись POM и код ниже для любого номера, страны и языка .
Вход POM
<dependency>
<groupId>com.ibm.icu</groupId>
<artifactId>icu4j</artifactId>
<version>64.2</version>
</dependency>
Код есть
public class TranslateNumberToWord {
/**

* @param ctryCd
* @param lang
* @param reqStr
* @param fractionUnitName
* @return
*/
public static String translate(String ctryCd, String lang, String reqStr, String fractionUnitName) {
StringBuffer result = new StringBuffer();
Locale locale = new Locale(lang, ctryCd);
Currency crncy = Currency.getInstance(locale);
String inputArr[] = StringUtils.split(new BigDecimal(reqStr).abs().toPlainString(), ".");
RuleBasedNumberFormat rule = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);
int i = 0;
for (String input : inputArr) {
CurrencyAmount crncyAmt = new CurrencyAmount(new BigDecimal(input), crncy);
if (i++ == 0) {
result.append(rule.format(crncyAmt)).append(" " + crncy.getDisplayName() + " and ");
} else {
result.append(rule.format(crncyAmt)).append(" " + fractionUnitName + " ");
}
}
return result.toString();
}
public static void main(String[] args) {

String lang = "en";
String input = "95.17";
String result = translate(ctryCd, lang, input, "Cents");
System.out.println("Input: " + input + " result: " + result);
}}
Протестировано с довольно большим числом, и результат будет
Input: 95.17 result: ninety-five US Dollar and seventeen Cents
Input: 999999999999999999.99 result: nine hundred ninety-nine quadrillion nine hundred ninety-nine trillion nine hundred ninety-nine billion nine hundred ninety-nine million nine hundred ninety-nine thousand nine hundred ninety-nine US Dollar and ninety-nine Cents
Вот очень простой класс NumberInWords.java с которым работа может быть выполнена очень легко:
String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six
Важно знать, что этот класс только способен преобразовывать тип данных int.
это может помочь
public String numberToWords(long number) {
if (number == 0) {
return "zero";
}
if (number < 0) {
return "minus " + numberToWords(Math.abs(number));
}
String words = "";
if ((number / 10000000) > 0) {
words += numberToWords(number / 10000000) + " Crore ";
number %= 10000000;
}
if ((number / 100000) > 0) {
words += numberToWords(number / 100000) + " Lakh ";
number %= 100000;
}
if ((number / 1000) > 0) {
words += numberToWords(number / 1000) + " Thousand ";
number %= 1000;
}
if ((number / 100) > 0) {
words += numberToWords(number / 100) + " Hundred ";
number %= 100;
}
if (number > 0) {
if (!words.equals("")) {
words += "and ";
}
if (number < 20) {

} else {

Возможно, вам это больше не нужно, но я недавно написал для этого класс java. Видимо, Яник Рочон сделал нечто подобное. Он преобразует числа до 999 ноябремдециллионов (999 * 10 ^ 60). Он мог бы сделать больше, если бы я знал, что было после Novemdecillion, но я готов поспорить, что в этом нет необходимости. Просто введите число в виде строки в центах. Вывод также грамматически правильный.
Вот ссылка на репозиторий Bitbucket
Я разработал компонент Java для преобразования заданного числа в слова. Все, что вам нужно сделать, это просто скопировать весь класс из Программа на Java для преобразования чисел в слова и вставки ее в свой проект.
Просто вызовите его, как показано ниже
Words w = Words.getInstance(1234567);
System.out.println(w.getNumberInWords());
Моя программа поддерживает до 10 миллионов. Если вы хотите, вы все равно можете продлить это. Чуть ниже примера вывода
2345223 = Twenty Three Lakh Fourty Five Thousand Two Hundred Twenty Three
9999999 = Ninety Nine Lakh Ninety Nine Thousand Nine Hundred Ninety Nine
199 = One Hundred Ninety Nine
10 = Ten
Спасибо
Сантош
Ниже программа на Java демонстрирует, как преобразовать число от нуля до миллиона.

Интуитивно понятное решение
1. Постройте отсортированную матрицу типа [значение - слово].
2. Найдите ближайшее значение из матрицы, для которого n / значение ›0 (можно использовать binary_search)
3. Рекурсивно построить левую и правую часть числа.
Ваш ответ: левая_часть + слово + правая_часть.
