Cómo convertir el número a palabras en java (26)
Actualmente tenemos un mecanismo tosco para convertir números en palabras (por ejemplo, usando unas pocas matrices estáticas) y en función del tamaño del número que lo traduce a texto en inglés. Pero nos encontramos con problemas para números que son enormes.
10183 = Ten thousand one hundred eighty three
90 = Ninety
5888 = Five thousand eight hundred eighty eight
¿Hay alguna función fácil de usar en cualquiera de las bibliotecas matemáticas que pueda usar para este propósito?
Como no puede tener un algoritmo general para cada localidad, no. Tienes que implementar tu propio algoritmo para cada localidad que estés apoyando.
** EDIT **
Solo por el placer de hacerlo, jugué hasta obtener esta clase. No puede mostrar Puede mostrar cualquier número hasta 66 dígitos y 26 decimales usando una representación de cadena del número. Puede agregar más Long.MIN_VALUE debido a restricciones de bit ... pero supongo que podría modificarse y cambiar long tipos de valor long para double para números decimales o incluso mayores ScaleUnit para obtener más decimales ...

ICU4J contiene buen soporte de número de deletreo. Los archivos con las "reglas" se pueden editar fácilmente, y no es un problema agregar otros idiomas (lo hicimos, por ejemplo, para polaco y ruso).
Here está el código, no creo que haya ningún método en SE.
Básicamente convierte número a cadena y analiza Cadena y lo asocia con el peso
por ejemplo
1000
1 se trata como mil posiciones y 1 se asigna a "one" y miles debido a la posición

I have written a clean version for 32-bit integers and american English:
I implemented it like this
package com.stack.overflow.number.in.english;
import java.util.ResourceBundle;
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
Integer numberOfDigits = number > 0 ? (int) Math.log10((double) number) + 1
: 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(number / power))
+ readPropertyFile.getString(String
.valueOf(power));
} else {
output += readPropertyFile.getString(String
.valueOf(number - number % power));
}
}
number = (int) (number % power);
}
}
}
return output;
}
}
and the resource file is :
0=zero
1=one
2=two
3=three
4=four
5=five
6=six
7=seven
8=eight
9=nine
10=ten
11=eleven
12=twelve
13=thirteen
14=fourteen
15fifteen

19=nineteen
20=twenty
30=thirty
40=fourty
50=fifty
60=sixty
70=seventy
80=eighty
90=ninety
100=hundred
1000=thousand
100000=Lakh
This one is implemented till 10 lakhs only
I think this may help you...programme is very simple and works fine

if (n > 19) {

}
public static void main(String[] args)

System.out.print("Enter an integer number: ");
n = s.nextInt();
if (n <= 0)
System.out.print("Enter numbers greater than 0");
else
{
NumberToWord a = new NumberToWord();
System.out.print("After conversion number in words is :");
a.pw((n / 1000000000), " Hundred");
a.pw((n / 10000000) % 100, " crore");
a.pw(((n / 100000) % 100), " lakh");
a.pw(((n / 1000) % 100), " thousand");
a.pw(((n / 100) % 10), " hundred");
a.pw((n % 100), " ");
}
}
}
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

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.

Take a look at Tradukisto . It''s a Java library I''ve written which does the job.

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.
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.
this might help
