We currently have a crude mechanism to convert numbers to words (e.g. using a few static arrays) and based on the size of the number translating that into an english text. But we are running into issues for numbers which are huge.
10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight
Is there an easy to use function in any of the math libraries which I can use for this purpose?
Here is the code, I don't think there is any method in SE.
It basically converts number to string and parses String and associates it with the weight
for example
1000
1 is treated as thousand position and 1 gets mapped to "one" and thousand because of position
This is the code from the website:

You can handle "dollar and cent" conversion by calling the "convert" method two times.
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" ;
Another way to use a built-in function of your DBMS (if available). For Oracle
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 contains nice number-spellout support. The files with the "rules" can be easily edited, and it's no problem to add other languages (we did it e.g. for Polish and Russian).
RuleBasedNumberFormat ruleBasedNumberFormat = new RuleBasedNumberFormat( new Locale("EN", "US"), RuleBasedNumberFormat.SPELLOUT ); System.out.println(ruleBasedNumberFormat.format(value)); –
Lavalley Because you cannot have a general algorithm for every locale, no. You have to implement your own algorithm for every locale that you are supporting.
** EDIT **
Just for the heck of it, I played around until I got this class. It cannot display It can display any numbers up to 66 digits and 26 decimals using a string representation of the number. You may add more Long.MIN_VALUE because of bit restrictions... but I presume it could be modified and change long value types to double for decimal or even bigger numbersScaleUnit for more decimals...

getName(string) is a convenient way to provide a number that is otherwise too big to be passed directly by value (ie. using a double). The example does not provide invalid output as it is assumed that the values have properly been validated. –
Gluttonous BigInteger and BigDecimal instead. That would've avoided the problem you are describing. –
Gluttonous I think that this solution is not the best, since it works only for int, but i think it's great for a beginner.

Take a look at Tradukisto. It's a Java library I've written which does the job.
You can use ICU4J, Just need to add POM entry and code is below for any Number, Country and Language.
POM Entry
<dependency>
<groupId>com.ibm.icu</groupId>
<artifactId>icu4j</artifactId>
<version>64.2</version>
</dependency>
Code is
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);
}}
Tested with quite a big number and output would be
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
In this post i have just update Yanick Rochon's code. I have make it workable with lower version of java 1.6 and i was getting the output for 1.00 = one and hundredth. So i have update the code. New i get the output for 1.00 = one and zero hundredth.
I don't not what should i do. Add a new answer or edit that post. As the answer is highly ranked so i have made a new post with updating the code. I have just change this two things have mention above.

Here is a very simple class NumberInWords.java that can have the job done very easily:
String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six
It's important to know that this class is only capable of converting int datatype.
You can use RuleBasedNumberFormat. for example result will give you 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);
It supports a wide range of languages.
I've developed a Java component to convert given number into words. All you've to do is - just copy the whole class from Java program to convert numbers to words and paste it in your project.
Just invoke it like below
Words w = Words.getInstance(1234567);
System.out.println(w.getNumberInWords());
My program supports up to 10 million. If you want, you can still extend this. Just below the example output
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
Thanks

You probably don't need this any more, but I recently wrote a java class to do this. Apparently Yanick Rochon did something similar. It will convert numbers up to 999 Novemdecillion (999*10^60). It could do more if I knew what came after Novemdecillion, but I would be willing to bet it's unnecessary. Just feed the number as a string in cents. The output is also grammatically correct.

Intuitive solution
1: Build a sorted matrix of [value - word] type
2: Find the closest value from matrix for which n/value > 0 (can use binary_search)
3: Recursively build the left and the right part of the number.
Your answer is left_part + word + right_part

Just simply call the convertToNumberName() function and give the numbers as string,to change from international to Indian, simply uncomment the commented lines in the function mentioned above, to add more number systems, more data sets and minor tweaking in the function will be required.
The stack mentioned here is just a simple LIFO structure and with ordinary stack functions, one could use their own custom implementation of the stack here or just import from Java.
The limit can be expanded further, for example, international number system only has capacity to convert up-to 999 billions, however, the data set can be expanded further to add trillions and quadrillions and more, it can go as far as the dataset that is the 3d array in code above allows it to.
