Displaying Currency in Indian Numbering Format

I have a question about formatting the Rupee currency (Indian Rupee - INR).

Typically a value like 450500 is formatted and shown as 450,500. In India, the same value is displayed as 4,50,500

For example, numbers here are represented as:

1
10
100
1,000
10,000
1,00,000
10,00,000
1,00,00,000
10,00,00,000

Refer Indian Numbering System

The separators are after two digits, except for the last set, which is in thousands.

I've searched on the internet and people have asked to use the locale en_GB or pattern #,##,##,##,##0.00

I tried this on JSTL by using the following tag:

<fmt:formatNumber value="${product.price}" type="currency" 
  pattern="#,##,##,##,###.00"/>

But this does not seem to solve the issue.

Unfortunately on standard Java SE DecimalFormat doesn't support variable-width groups. So it won't ever format the values exactly as you want to:

> If you supply a pattern with multiple grouping characters, the interval between the last one and the end of the integer is the one that is used. So "#,##,###,####" == "######,####" == "##,####,####".

Most number formatting mechanisms in Java are based on that class and therefore inherit this flaw.

ICU4J (the Java version of the International Components for Unicode) provides a NumberFormat class that does support this formatting:

Format format = com.ibm.icu.text.NumberFormat.getCurrencyInstance(new Locale("en", "in"));
System.out.println(format.format(new BigDecimal("100000000")));

This code will produce this output:

Rs 10,00,00,000.00

Note: the com.ibm.icu.text.NumberFormat class does not extend the java.text.NumberFormat class (because it already extends an ICU-internal base class), it does however extend the java.text.Format class, which has the format(Object) method.

Note that the Android version of java.text.DecimalFormat class is implemented using ICU under the hood and does support the feature in the same way that the ICU class itself does (even though the summary incorrectly mentions that it's not supported).

With Android, this worked for me:

new DecimalFormat("##,##,##0").format(amount);

450500 gets formatted as 4,50,500

http://developer.android.com/reference/java/text/DecimalFormat.html - DecimalFormat supports two grouping sizes - the primary grouping size, and one used for all others.

here is simple thing u can do ,

 float amount = 100000;

 NumberFormat formatter = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));

 String moneyString = formatter.format(amount);

 System.out.println(moneyString);

The output will be Rs.100,000.00.

I also got myself in same problem. I was working with DecimalFormat.

I have no knowledge of JSTL but you can figure out something by my solution.

As, grouping size remains constant in DecimalFormat. I separated both parts, formatted them with different patterns and concat both. Here is the code.

public static String format(double value) {
    if(value < 1000) {
        return format("###", value);
    } else {
        double hundreds = value % 1000;
        int other = (int) (value / 1000);
        return format(",##", other) + ',' + format("000", hundreds);
    }
}

private static String format(String pattern, Object value) {
    return new DecimalFormat(pattern).format(value);
}

It will provide format like Indian Numbering System.

If you want decimal points, just add ".##" in both conditions.

"###" to "###.##" and "000" to "000.##".

Just Copy past this function. :)

  public static String rupeeFormat(String value){
            value=value.replace(",","");
            char lastDigit=value.charAt(value.length()-1);
            String result = "";
            int len = value.length()-1;
            int nDigits = 0;
    
            for (int i = len - 1; i >= 0; i--)
            {
                result = value.charAt(i) + result;
                nDigits++;
                if (((nDigits % 2) == 0) && (i > 0))
                {
                    result = "," + result;
                }
            }
            return (result+lastDigit);
        }

public String getIndianCurrencyFormat(String amount) {
    StringBuilder stringBuilder = new StringBuilder();
    char amountArray[] = amount.toCharArray();
    int a = 0, b = 0;
    for (int i = amountArray.length - 1; i >= 0; i--) {
        if (a < 3) {
            stringBuilder.append(amountArray[i]);
            a++;
        } else if (b < 2) {
            if (b == 0) {
                stringBuilder.append(",");
                stringBuilder.append(amountArray[i]);
                b++;
            } else {
                stringBuilder.append(amountArray[i]);
                b = 0;
            }
        }
    }
    return stringBuilder.reverse().toString();
}

This is what i did, for getting Indian currency format. if input is 1234567890 means output is 1,23,45,67,890.

Try this:

NumberFormat.getCurrencyInstance(new Locale("en","IN")).format(number)

"en" is for English. "IN" is for the country (India).

The simple solution is -

Double amount = 5356673553123.0; //amount is an example ,can be used with any double value

**DecimalFormat IndianCurrencyFormat = new DecimalFormat("##,##,###.00");**

then use it as -

String formattedAmount = IndianCurrencyFormat.format(amount);

Please find below snippet to print currency according to locale by giving inputs

import java.util.*;
import java.text.*;

public class CurrencyPayment {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double payment = scanner.nextDouble();
        scanner.close();

        System.out.println("US: " + NumberFormat.getCurrencyInstance(Locale.US).format(payment));
        System.out.println("India: " + NumberFormat.getCurrencyInstance(new Locale("en","IN")).format(payment));
        System.out.println("China: " + NumberFormat.getCurrencyInstance(Locale.CHINA).format(payment));
        System.out.println("France: " + NumberFormat.getCurrencyInstance(Locale.FRANCE).format(payment));
    }
}

If there is no default Locale available and the user doesn't make any change to the locale, we can go with setting the currency symbol using unicode and decimal formatting. As in the below code:

For e.g. Setting the Indian currency symbol and formatting the value. This will work without user making changes in the settings.

    Locale locale = new Locale("en","IN");
    DecimalFormat decimalFormat = (DecimalFormat) DecimalFormat.getCurrencyInstance(locale);
    DecimalFormatSymbols dfs = DecimalFormatSymbols.getInstance(locale);
    dfs.setCurrencySymbol("\u20B9");
    decimalFormat.setDecimalFormatSymbols(dfs);
    System.out.println(decimalFormat.format(payment));

Output:

₹12,324.13

On Android android.icu.text.NumberFormat is available after api level 24 only. So to support lower version I wrote my own method in java.

public static String formatIndianCommaSeparated(long rupee){
    // remove sign if present
    String raw = String.valueOf(Math.abs(rupee));
    int numDigits = raw.length();
    StringBuilder sb = new StringBuilder(raw);
    // Reverse the string to start from right most digits
    sb = sb.reverse();
    // Counter to keep track of number of commas placed
    int commas = 0;
    for (int i=0; i<numDigits; i++){
        // Insert a comma if i is in the range [3, 5, 7, 9, ...)
        if (i % 2 == 1 && i != 1 ){
            sb.insert(i+commas, ",");
            commas++;
        }
    }
    // Reverse the string back to get original number
    String sign = (rupee < 0) ? "-" : "";
    return sign + sb.reverse().toString();
}

Kotlin version, It works on Android API 26

fun currencyLocale(value: Double): String {
    val formatter = NumberFormat.getCurrencyInstance(Locale("en", "in"))
    return formatter.format(value)
}

fun parseCommaSeparatedCurrency(value: String): Number {
    return NumberFormat.getCurrencyInstance(Locale("en", "in")).parse(value)
}

Few options that I explored are as below

	import java.text.NumberFormat;
	import java.util.Locale;

	class NumberFormatDemo {

		public static void main(String[] args) {
			Double d = 45124853123456.78941;
			NumberFormat nf = NumberFormat.getInstance(Locale.ITALY);
			System.out.println("ITALY representation of " + d + " : " + nf.format(d));

			nf = NumberFormat.getInstance(Locale.GERMANY);
			System.out.println("GERMANY representation of " + d + " : " + nf.format(d));

			nf = NumberFormat.getInstance(Locale.CHINESE);
			System.out.println("CHINESE representation of " + d + " : " + nf.format(d));

			nf = NumberFormat.getInstance(Locale.US);
			System.out.println("US representation of " + d + " : " + nf.format(d));

			nf = NumberFormat.getInstance(Locale.ENGLISH);
			System.out.println("ENGLISH representation of " + d + " : " + nf.format(d));

			nf = NumberFormat.getInstance(Locale.UK);
			System.out.println("UK representation of " + d + " : " + nf.format(d));

			//===================================================
			//ICU4j example
			com.ibm.icu.text.NumberFormat format = com.ibm.icu.text.NumberFormat.getCurrencyInstance(new Locale("en", "in"));
			System.out.println("INDIA representation of " + d + " : " + nf.format(d));
		}
	}

The last one reacquires following dependency

<dependency>
<groupId>com.ibm.icu</groupId>
<artifactId>icu4j</artifactId>
<version>65.1</version>
</dependency>

//Input:
long num = 450500;

// Unlike other countries, there is no direct Locale field for India.Therefore, we need to construct a locale for India.
Locale loc = new Locale("en", "in"); // This will display currency with "Rs." symbol.

// or use below to display currency with "INR" symbol.
Locale loc = new Locale("", "in");

NumberFormat indiacurrency = NumberFormat.getCurrencyInstance(loc);
String result = indiacurrency.format(num);
System.out.print(result);

public static String paiseToString(long paise)
{
    DecimalFormat fmt = new DecimalFormat("#0.00");
    boolean minus = paise < 0;
    StringBuilder sb = new StringBuilder(fmt.format(Math.abs(paise)/100.0));
    for (int index = sb.length()-6; index > 0; index-=2)
    {
        sb.insert(index,',');
    }
    if (minus)
       sb.insert(0,'-');
    return sb.toString();
}

public static String rupeesToString(long rupees)
{
    boolean minus = rupees < 0;
    StringBuilder sb = new StringBuilder(Long.toString(Math.abs(rupees)));
    for (int index = sb.length()-3; index > 0; index-=2)
    {
        sb.insert(index,',');
    }
    if (minus)
       sb.insert(0,'-');
    return sb.toString();
}

// Test the functions
public static void main(String[] args)
{
    // Test for positive values
    long val = 1;
    while (val < Long.MAX_VALUE/10)
    {
        System.out.printf("%28s %28s\n",paiseToString(val),rupeesToString(val));
        val *= 10;
    }
    // Test for negative values
    val = -1;
    while (val > Long.MIN_VALUE/10)
    {
        System.out.printf("%28s %28s\n",paiseToString(val),rupeesToString(val));
        val *= 10;
    }	    
}

The default methods in existing libraries can only show thousands seperator. so we need to write custom function for this. You can use multiple substring operation to get the desired result.

In java,

function indianCurrencyNumberFormat(rupee) {
    string explore_remaining_units = "";
    if (rupee.length() > 3) {
        last_three_digits = rupee.substring((rupee.length()-3), rupee.length());
        remaining_units = rupee.substring(0, (rupee.length()-3)); 
        remaining_units =  ((remaining_units.length()) % 2 == 1) ? "0"+remaining_units : remaining_units; 
        split_rupee = remaining_units.split("(?<=^(.{2})+)")
        for (i = 0; i < sizeof(split_rupee); i++) {
          explore_remaining_units += ((i == 0) ? ( (int) split_rupee[i]+"," ) : ( split_rupee[i]+"," ));  
        }
        formatted_rupee = explore_remaining_units+last_three_digits;
    } else {
        formatted_rupee = rupee;
    }
    return formatted_rupee; 
}

And in php:

function indianCurrencyNumberFormat($rupee) {
    $explore_remaining_units = "";
    if (strlen($rupee) > 3) {
        $last_three_digits = substr($rupee, strlen($rupee) - 3, strlen($rupee));
        $remaining_units = substr($rupee, 0, strlen($rupee) - 3); 
        $remaining_units = (strlen($remaining_units) % 2 == 1) ? "0".$remaining_units : $remaining_units; 
        $split_rupee = str_split($remaining_units, 2);
        for ($i = 0; $i < sizeof($split_rupee); $i++) {
          $explore_remaining_units .= (($i == 0) ? ( (int) $split_rupee[$i] . "," ) : ( $split_rupee[$i] . "," ));  
        }
        $formatted_rupee = $explore_remaining_units.$last_three_digits;
    } else {
        $formatted_rupee = $rupee;
    }
    return $formatted_rupee; 
}

It is better answer and works dynamically instead of specifying single Locale in code manually.

public String convertToDefaultCurrencyFormat(String amountToConvert){
    NumberFormat formatter = NumberFormat.getCurrencyInstance(Locale.getDefault());
    String moneyString = formatter.format(Double.valueOf(amountToConvert));
    return moneyString;
}   

for Indian rupees format change Language in your Android device:

Setting > Language & Input Settings > choose English(India)

Output:

₹10,00,000 (Starting with Indian Rupee symbol)

Working fine for me in Android:

public static String priceFormatWithDec(String price) {
    DecimalFormat decimalFormat = new DecimalFormat("#,##,###.00");
    String format = decimalFormat.format(Double.parseDouble(price));
    return String.format("%s", format);
}

using Locale class and getCurrencyInstance the Indian currency format can be obtained.

while defining the new Locale for India use "en" for English and "hi" for Hindi.

for locale refer https://docs.oracle.com/javase/8/docs/api/java/util/Locale.html

for getCurrencyInstance refer https://docs.oracle.com/javase/8/docs/api/java/text/NumberFormat.html#getCurrencyInstance--

here is a small implementation of the same.

import java.util.*;
import java.text.*;
import java.text.NumberFormat;
import java.util.Locale;

public class Solution {
 
    public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    double payment = scanner.nextDouble();
    scanner.close();
      
    Locale indialocale=new Locale("en","IN");
	NumberFormat india  = NumberFormat.getCurrencyInstance(indialocale);
    System.out.println("India: " + india.format(payment));
    }

}

This is working for me ..

public String indianCurrencyFormat(String s) {

	String orignalNo = s;
	String formatted = "";

	if(orignalNo.startsWith("-")) {
		s = s.replace("-","");
	}

	if(orignalNo.contains(".")) {

			while(s.length() > 1) {
				formatted += "," + s.substring(0,2);
				s = s.substring(2);
			}

			sb = new StringBuilder(formatted+(StringUtils.isNotBlank(s) ? ","+s :""));
			formatted = sb.reverse().toString();
		} else {
			formatted = s;
		}
	} else {

			formatted = s.substring(0,3);

			}

I know this is an old question but I'll add my answer just in case. It is possible to use the same decimal formatter in a roundabout way to achieve the result but it isn't the most efficient solution, just a simpler one.

import java.math.RoundingMode;
import java.text.DecimalFormat;

public class IndianMoneyFormat {

    static String indianCurrencyFormat(double money) {
        String result = null;

        double aboveThousands = money / 1000;
        double thousands = money % 1000;

        if (aboveThousands > 1) {
            DecimalFormat formatter = new DecimalFormat("##,##");
            formatter.setRoundingMode(RoundingMode.DOWN); //will round towards zero whether negative or positive. Same as truncating.
            String one = formatter.format(aboveThousands);

            formatter.applyPattern("###.00");
            formatter.setRoundingMode(RoundingMode.HALF_EVEN); //default rounding mode of DecimalFormat
            String two = formatter.format(thousands);

            result = one + "," + two;
            return result;
        } else {
            DecimalFormat formatter = new DecimalFormat("###.00");
            result = formatter.format(money);
            return result;
        }
    }

    public static void main(String[] args) {
        double money1 = 123000999.5;
        double money2 = 999.39;
        System.out.println(indianCurrencyFormat(money1));
        System.out.println(indianCurrencyFormat(money2));
    }
}

Above code will provide the following result:

12,30,00,999.50
999.39
