Is there any way to make the pennies not cut with float type?

I am converting a value to be formatted with Decimalformat so that it looks like the pennies this way:

    Float numero = 2564786549.87543771885808f;
    DecimalFormat df = new DecimalFormat("0.00");  
    System.out.println(df.format(numero));

I need to be shown this:

2564786432,54

Only this way you’re zeroing out the pennies, you’d be able to keep it?

Ps.: I cannot use double.

    For coins, it is recommended to use Bigdecimal, or you will have disadvantages (or your customer rs) because float and double are terrible when it comes to decimal accuracy.

    Taking advantage of the previous comment, check based on Bigdecimal the formatting you want. http://stackoverflow.com/questions/5195837/format-float-to-n-decimal-places

  • I’ll switch to this one, wait.

    You can’t even use double, nor float. This is a mistake that you can’t fix without using the right guy, even if it looks like you did and that’s a danger because it’s easy to make it look like you did.

  • Okay, got it... I’ve never used Bigdecimal before

Hello, I recommend reading Formatting Numeric Print Output will be useful!

Excerpt from the source: These methods, format and printf, are equivalent to one other!

import java.util.Calendar;
import java.util.Locale;

public class TestFormat {

    public static void main(String[] args) {
      long n = 461012;
      System.out.format("%d%n", n);      //  -->  "461012"
      System.out.format("%08d%n", n);    //  -->  "00461012"
      System.out.format("%+8d%n", n);    //  -->  " +461012"
      System.out.format("%,8d%n", n);    // -->  " 461,012"
      System.out.format("%+,8d%n%n", n); //  -->  "+461,012"

      double pi = Math.PI;

      System.out.format("%f%n", pi);       // -->  "3.141593"
      System.out.format("%.3f%n", pi);     // -->  "3.142"
      System.out.format("%10.3f%n", pi);   // -->  "     3.142"
      System.out.format("%-10.3f%n", pi);  // -->  "3.142"
      System.out.format(Locale.FRANCE,
                        "%-10.4f%n%n", pi); // -->  "3,1416"

      Calendar c = Calendar.getInstance();
      System.out.format("%tB %te, %tY%n", c, c, c); // -->  "May 29, 2006"

      System.out.format("%tl:%tM %tp%n", c, c, c);  // -->  "2:34 am"

      System.out.format("%tD%n", c);    // -->  "05/29/06"
    }
}
