Thread: Question: Converting cents to dollars.

Hi, this is the output of the program I made:

Enter amount in nickels: 2
Enter amount in pennies: 100
 
You entered 2 nickels and 100 pennies.
 
 
The total amount in penny is 110.0
The total amount in nickel is 22.0
 
Converting the amount of nickel and penny into dollar...
 
 
[B]The total amount in dollar is 1.1[/B]

How can it be like this:

Enter amount in nickels: 2
Enter amount in pennies: 100
 
You entered 2 nickels and 100 pennies.
 
 
The total amount in penny is 110.0
The total amount in nickel is 22.0
 
Converting the amount of nickel and penny into dollar...
 
 
[B]The total amount is 1 dollar and 10 cents.[/B]

What should I do?

You can convert your final dollar amount into a string, then parse the string to determine if/where the decimal point is and use that is a guide. For example

String s = Float.parseFloat(dollarAmount);//assuming dollarAmount is a float containing the value
int loc = -1;
String dollars, cents;
if ( (loc = s.indexOf(".")) != -1 ){
   dollars = s.substring( 0, loc );
   cents = s.substring( loc, s.length() );
    ///get the first two digits from cents here.
}else{
    dollars = s;
    cents = "0";
}

@ ALL:

Hi thank you for your reply. Sorry I did not specify that I cannot use advanced coding. I need simple codes for this.

Someone gave me this advice:

you get the dollars by taking int(cents / 100)
you get the cents by taking cents mod 100
you have to use if statement to check if it's 0 cents (don't show it), 1 cent (use cent instead of cents) or more (use cents)

But I do not know how to use these.

This is my program that outputs the "The total amount in dollar is 1.1":

import java.io.*;
 
public class CentsDollar {
 
    public static void main (String[]args) {
 
        BufferedReader input = new BufferedReader (new InputStreamReader(System.in));
 
        String x="";
 
        try {
            System.out.println("Enter amount in nickel: ");
            x = input.readLine();
            int nickelin = Integer.parseInt(x);
 
            System.out.println("Enter amount in penny: ");
            x = input.readLine();
            int penniesin = Integer.parseInt(x);
 
            double pennies = (nickelin*5)+(penniesin);
            double nickel = (pennies/5);
 
            System.out.println("You entered " +nickelin+ " nickels and " +penniesin+ " pennies.\n");
            System.out.println("The total amount in penny is "+pennies+".");
            System.out.println("The total amount in nickel is "+nickel+".\n");
            System.out.println("Converting the amount of nickel and penny into dollar...\n\n");
 
            double dollar = (pennies/100);
 
 
            System.out.println("The total amount in dollar is " +dollar+"." );
        }
 
        catch (IOException e) {
            System.out.println("Error!");
        }
    }
 
}

Where do I insert the if statement? How do I use the "mod"?
