Як перетворити число в слова на Java


132

Наразі у нас є сильний механізм перетворення чисел у слова (наприклад, за допомогою декількох статичних масивів) та на основі розміру числа, що переводить його в англійський текст. Але ми стикаємося з проблемами для величезних цифр.

10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight

Чи є в будь-якій математичній бібліотеці функцію, яку я простий у використанні, я можу використовувати для цього?

Ось код, я не думаю, що в SE існує якийсь метод.

Він в основному перетворює число в рядок і аналізує рядок і пов'язує його з вагою

наприклад

1000

1трактується як тисяча позиції і 1отримує відображення до "one"тисячі через позицію

Ви можете обробити конвертацію "долар і цент", викликавши метод "конвертувати" два рази.

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" ;

Я взяв ваш код для французької версії і переніс його на groovy, змушуючи його працювати для більшої кількості. Це досить легко змусити його працювати з ще більшими. Якщо хтось зацікавлений, це тут . Дякуємо за основний матеріал!

Програма дає неправильний вихід, коли ви вводите 100500, але в інших випадках працює нормально

Тому що ви не можете мати загальний алгоритм для кожної локалі, ні. Ви повинні реалізувати власний алгоритм для кожної локалі, яку ви підтримуєте.

Просто для чорта, я грав, поки не отримав цей клас. Він не може відображатись Long.MIN_VALUEчерез бітові обмеження ... але я припускаю, що це може бути змінено та змінити longтипи значень doubleна десяткові або навіть більші числаВін може відображати будь-які числа до 66 цифр і 26 десяткових знаків, використовуючи рядкове представлення числа. Ви можете додати більше ScaleUnitдля десяткових знаків ...

@Don Roby - AFAIK, це лише історична проблема. Більшість британських людей сьогодні використовують американську англійську мову. (Звичайно, є кілька ексцентриків, які пишуть листи (зеленою фарбою) до The Times про подібні речі, але вони, мабуть, не помітять через те, що відмовляються вчитися користуватися комп’ютерами :-))

@Rochon: Хороший код !! Допомогли мені дуже багато ... але має невелику помилку..test з "10.00" ... для видалення цієї помилки хочеться додати трохи виправлення під час перетворення рядка в слово, int indexOfDecimal = value.indexOf ("."); Рядок десяткового = value.substring (indexOfDecimal + 1, value.length ()); BigDecimal decimalValue = новий BigDecimal (десятковий); if (decimalValue.compareTo (BigDecimal.ZERO) == 0) value = value.substring (0, indexOfDecimal);

ICU4J містить хорошу підтримку кількості записів. Файли з "правилами" можна легко редагувати, і це не проблема, щоб додати інші мови (ми це зробили, наприклад, для польської та російської).


Дані ICU4J походить від CLDR unicode.org/cldr і вже підтримує польський і російський. unicode.org/repos/cldr/trunk/common/rbnf Ви подали квиток, якщо виявили проблеми з існуючими правилами?

Ні, але ми це робили кілька років тому, і якщо я правильно пам’ятаю, нам потрібні були додаткові речі. Але добре знати!

Погляньте на Традукісто . Я написав бібліотеку Java, яка виконує цю роботу.

Чи є причина, чому всі ці відповіді мають погану граматику? «Тисяча двісті тридцять чотири» повинна бути «одна тисяча двісті і 30-чотири». Це якась банківська англійська мова, про яку я не знаю?

@weston В американській англійській мові "і" не використовується. Це тільки в англійській англійській мові.

У цій публікації я щойно оновив код Яніка Рошона . Я зробив це працездатним з нижчою версією java 1.6, і я отримував вихід 1,00 = одна сота . Отже, у мене є оновлення коду. Новий я отримую вихід за 1,00 = один і нульовий сотий .

Я не те, що мені робити. Додайте нову відповідь або відредагуйте цю публікацію. Оскільки відповідь високо оцінений, тому я зробив нову посаду з оновленням коду. Я просто змінив ці дві речі, про які згадувалося вище.

Ви можете використовувати RuleBasedNumberFormat. наприклад, результат дасть вамNinety

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);

Він підтримує широкий спектр мов.

Вам, мабуть, це вже не потрібно, але я нещодавно написав клас java для цього. Мабуть, Янік Рошон зробив щось подібне. Він перетворить числа до 999 Новемдекліонів (999 * 10 ^ 60). Це могло б зробити більше, якби я знав, що відбудеться після Novemdecillion, але я був би готовий зробити ставку на непотрібність. Просто введіть число у вигляді рядка в центах. Вихід також граматично правильний.

Я розробив компонент Java для перетворення заданого числа у слова. Все, що вам потрібно зробити - просто скопіювати весь клас з програми Java для перетворення чисел у слова та вставити їх у проект.

Просто попросіть його, як показано нижче

Words w = Words.getInstance(1234567);
System.out.println(w.getNumberInWords());

Моя програма підтримує до 10 мільйонів. Якщо хочете, ви можете продовжити це. Трохи нижче прикладу виведення

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

Дякую

Ось дуже простий клас NumberInWords.java, який може зробити цю роботу дуже легко:

String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six

Важливо знати , що цей клас тільки здатний перетворювати тип даних Int.
