我们目前有一个粗略的机制来将数字转换为单词（例如，使用一些静态数组）并根据数字的大小将其转换为英文文本。但是我们遇到了巨大的数字问题。
10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight
我可以为此目的使用的任何数学库中是否有易于使用的函数？

这是代码，我认为SE中没有任何方法。
它基本上将数字转换为字符串并解析字符串并将其与权重相关联
例如
1000
1被视为千位并由于位置而1被映射到"one"千位
这是来自网站的代码：

您可以通过调用“convert”方法两次来处理“美元和美分”的转换。
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" ;
另一种使用 DBMS 内置功能的方法（如果可用）。对于甲骨文
SQL> select to_char(to_date(873,'J'), 'JSP') as converted_form from dual;
CONVERTED_FORM
---------------------------
EIGHT HUNDRED SEVENTY-THREE
SQL>
'JSP' means :
J : the Julian format.
SP : spells the word for the number passed to to_date

ICU4J包含很好的数字拼写支持。带有“规则”的文件可以轻松编辑，添加其他语言也没问题（例如波兰语和俄语）。

因为你不能对每个语言环境都有一个通用算法，所以没有。您必须为您支持的每个语言环境实现自己的算法。
**编辑**
只是为了它，我一直玩到我上了这门课。由于位限制，它无法显示它可以使用数字的字符串表示形式显示最多 66 位和 26 位小数的任何数字。您可以添加更多Long.MIN_VALUE......但我认为它可以被修改并将long值类型更改double为十进制甚至更大的数字ScaleUnit以获得更多小数...

我认为这个解决方案不是最好的，因为它只适用于int，但我认为它对初学者来说很棒。
public class NumberWordConverter {
public static final String[] units = {
"", "one", "two", "three", "four", "five", "six", "seven",
"eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen",
"fifteen", "sixteen", "seventeen", "eighteen", "nineteen"

public static final String[] tens = {
"", // 0

"twenty", // 2
"thirty", // 3
"forty", // 4
"fifty", // 5
"sixty", // 6

"eighty", // 8
"ninety" // 9
};
public static String convert(final int n) {
if (n < 0) {
return "minus " + convert(-n);
}
if (n < 20) {
return units[n];
}
if (n < 100) {
return tens[n / 10] + ((n % 10 != 0) ? " " : "") + units[n % 10];
}
if (n < 1000) {

}

return convert(n / 1000) + " thousand" + ((n % 1000 != 0) ? " " : "") + convert(n % 1000);
}

return convert(n / 1000000) + " million" + ((n % 1000000 != 0) ? " " : "") + convert(n % 1000000);
}
return convert(n / 1000000000) + " billion" + ((n % 1000000000 != 0) ? " " : "") + convert(n % 1000000000);
}
public static void main(final String[] args) {
final Random generator = new Random();
int n;
for (int i = 0; i < 20; i++) {
n = generator.nextInt(Integer.MAX_VALUE);
System.out.printf("%10d = '%s'%n", n, convert(n));
}

System.out.printf("%10d = '%s'%n", n, convert(n));
n = Integer.MAX_VALUE;
System.out.printf("%10d = '%s'%n", n, convert(n));
}
}

在这篇文章中，我刚刚更新了Yanick Rochon 的代码。我已经使它适用于较低版本的 java 1.6 并且我得到了1.00 = one and percentth的输出。所以我更新了代码。新我得到1.00 = 百分之一和百分之零的输出。
我不知道我应该怎么做。添加新答案或编辑该帖子。由于答案排名很高，所以我发布了一个更新代码的新帖子。我刚刚改变了上面提到的这两件事。

您可以使用 RuleBasedNumberFormat。例如结果会给你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);
它支持多种语言。

您可以使用ICU4J，只需添加 POM 条目，代码如下所示，适用于任何数字、国家和语言。
POM 条目
<dependency>
<groupId>com.ibm.icu</groupId>
<artifactId>icu4j</artifactId>
<version>64.2</version>
</dependency>
代码是
public class TranslateNumberToWord {
/**
* Translate
*
* @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 ctryCd = "US";
String lang = "en";
String input = "95.17";
String result = translate(ctryCd, lang, input, "Cents");
System.out.println("Input: " + input + " result: " + result);
}}
用相当大的数字进行测试，输出将是
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

这是一个非常简单的类NumberInWords.java可以很容易地完成工作：
String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six
重要的是要知道这个类只能转换 int 数据类型。

我开发了一个 Java 组件来将给定的数字转换为单词。您所要做的就是 - 只需从Java 程序中复制整个类以将数字转换为单词并将其粘贴到您的项目中。
只需像下面这样调用它
Words w = Words.getInstance(1234567);
System.out.println(w.getNumberInWords());
我的程序最多支持1000万。如果你愿意，你仍然可以扩展它。就在示例输出下方
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
谢谢

你可能不再需要这个了，但我最近写了一个 java 类来做这个。显然 Yanick Rochon 做了类似的事情。它将转换数字高达 999 Novemdecillion (999*10^60)。如果我知道 Novemdecillion 之后会发生什么，它可以做得更多，但我愿意打赌这是不必要的。只需将数字作为以美分为单位的字符串输入。输出在语法上也是正确的。

我是这样实现的
package com.stack.overflow.number.in.english;

public class ActualImplementation {
public static ResourceBundle readPropertyFile = ResourceBundle
.getBundle("NumberEnglishRepresentation");
public static void main(String[] args) {

}
public static String main(Integer number) {
int power;
// Calculate Number of digits

: 1;
String output = "";
// If number is negative convert it to positive an append minus to
// output
if (Integer.signum(number) == -1) {
output = "minus ";
number = number < 0 ? number * -1 : number;
}
String stringVal = String.valueOf(number);
if (number <= 20 || number == 30 || number == 40 || number == 50
|| number == 60 || number == 70 || number == 80 || number == 90
|| number == 100 || number == 1000)
output += readPropertyFile.getString(stringVal);
else {
int i;
for (i = 0; i < numberOfDigits; i++) {
if (number != 0) {
numberOfDigits = number > 0 ? (int) Math
.log10((double) number) + 1 : 1;
power = (int) Math.pow(10, numberOfDigits - 1);
// If number is like 10,001 then print ten first and then
// remaining value
if (numberOfDigits >= 5 && numberOfDigits % 2 == 1) {
power = (int) Math.pow(10, numberOfDigits - 2);
}
if (readPropertyFile.containsKey(String.valueOf(number)))
output += readPropertyFile.getString(String
.valueOf(number));
else {
// As the digits at units and tens place are read
// differently
if (numberOfDigits > 2) {
output += readPropertyFile.getString(String

.valueOf(power));
} else {
output += readPropertyFile.getString(String

}
}
number = (int) (number % power);
}
}
}
return output;
}
}

找到这个印度卢比的代码，比百万和十亿还多。您可以将 String 或 Bigdecimal 传递给该方法。这也将为派萨提供正确的输出。
package yourpackage;
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
public class Currency {
public static String convertToWords(BigDecimal num) {
return convertToWords(num.toString());

public static String convertToWords(String num) {
BigDecimal bd = new BigDecimal(num);
long number = bd.longValue();
long no = bd.longValue();
int decimal = (int) (bd.remainder(BigDecimal.ONE).doubleValue() * 100);
int digits_length = String.valueOf(no).length();
int i = 0;
ArrayList<String> str = new ArrayList<>();
HashMap<Integer, String> words = new HashMap<>();
words.put(0, "");
words.put(1, "One");

String digits[] = { "", "Hundred", "Thousand", "Lakh", "Crore" };
while (i < digits_length) {
int divider = (i == 2) ? 10 : 100;
number = no % divider;
no = no / divider;
i += divider == 10 ? 1 : 2;
if (number > 0) {
int counter = str.size();
String plural = (counter > 0 && number > 9) ? "s" : "";
String tmp = (number < 21) ? words.get(Integer.valueOf((int) number)) + " " + digits[counter] + plural
: words.get(Integer.valueOf((int) Math.floor(number / 10) * 10)) + " "
+ words.get(Integer.valueOf((int) (number % 10))) + " " + digits[counter] + plural;
str.add(tmp);
} else {
str.add("");
}
}
Collections.reverse(str);
String Rupees = String.join(" ", str).trim();
String paise = (decimal) > 0
? " And " + words.get(Integer.valueOf((int) (decimal - decimal % 10))) + " "
+ words.get(Integer.valueOf((int) (decimal % 10))) + " Paise "
: "";
return "Rupees " + Rupees + paise + " Only";
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
System.out.println("56721351 = " + Currency.convertToWords(new BigDecimal(56721351)));
System.out.println("76521351.61 = " + Currency.convertToWords("76521351.61"));
}
}
当您为 56721351（作为 Bigdecimal）和 76521351.61（作为字符串）运行此程序时，输出为
56721351 = Rupees Five Crore Sixty Seven Lakhs Twenty One Thousands Three Hundred Fifty One Only
76521351.61 = Rupees Seven Crore Sixty Five Lakhs Twenty One Thousands Three Hundred Fifty One And Sixty One Paise Only
