java - Formating numbers with %1$,.2f -

i using

public static string displaynumberamount(number amount, locale locale) {     string.format(locale, "%1$,.2f", amount); } 

to format numbers in locale , 2 decimals.

if have number 1032 correctly formatted 1 032,00 if have number lower 1000, example 890, formatted 890 (and need 2 decimals always)

in object, values stored bigdecimals,

bigdecimal val = object.getamount(); string formattedval = displaynumberamount(val, mylocale); 

can tell me why?

your code works fine me. test:

import java.math.bigdecimal; import java.util.locale;  public class tester{     public static void main(string args[]){         system.out.println("999 " + displaynumberamount(new bigdecimal(999.99), locale.french));         system.out.println("1000 " + displaynumberamount(new bigdecimal(1000.99), locale.french));         system.out.println("1001 " + displaynumberamount(new bigdecimal(1001.99), locale.french));     }      public static string displaynumberamount(number amount, locale locale) {         return string.format(locale, "%1$,.2f", amount);     }  }
