Need help with this program

import java.util.Scanner;
public class PP_2_11a
{
//---------------------------------------------------------------------
// Reads amount of money and determines what bills and coins are needed
//---------------------------------------------------------------------

public static void main (String[]args)
{
double total_amount;
Scanner scan = new Scanner (System.in);



boolean more = true;

while (more)
{
System.out.println ("Enter amount of money.");
total_amount = scan.nextDouble();


int tens = (int)total_amount/10;
total_amount = total_amount%10;
int fives = (int)total_amount/5;
total_amount = total_amount%5;
int ones = (int)total_amount/1;
total_amount = total_amount%1;
int quarters = (int)(total_amount/.25);
total_amount = (total_amount%.25);
int dimes = (int)(total_amount/.10);
total_amount = (total_amount%.10);
int nickels = (int)(total_amount/.05);
total_amount = (total_amount%.05);
int pennies = (int)(total_amount%.01);



System.out.println (tens + " ten dollar bills");
System.out.println (fives + " five dollar bills");
System.out.println (ones + " one dollar bills");
System.out.println (quarters + " quarters");
System.out.println (dimes + " dimes");
System.out.println (nickels + " nickels");
System.out.println (pennies + " pennies");

System.out.print ("Enter 1 to continue, 0 to quit > ");
more = (1 == scan.nextInt());
}


}
}

Please explain what the code should do.
Copy and paste here the contents of the console screen from when you run the program
Add some comment to the output saying what the output should be.

There are some problems working with floating point numbers.

One trick is to convert the amount to cents and scale your divisors accordingly.

my program needs to be able to read the amount of money and then output how many tens, fives, ones, quarters, dimes and so on that are needed to make the amount.
When I run the program it does everything right except it does not calculate the amount of pennies right:
----jGRASP exec: java PP_2_11a

Enter amount of money.
68.97
6 ten dollar bills
1 five dollar bills
3 one dollar bills
3 quarters
2 dimes
0 nickels
1 pennies
Enter 1 to continue, 0 to quit >

there should be 2 pennies but I do not understand why it is not calculating it right.

Add some printlns in your code to print out the intermediate values so you can see what is happening.

I was able to find out where it went wrong when I put in the printlns-thank you!
