Thread: Java Change Maker need help with rounding up the pennies

So im new to programing and need help solving my program because my teacher never taught us about how to solve the issue. it works and compiles as of right now but if you run it. the issue is when i input for ex. .92 cents for the total bill and i input 1 dollar for tendered i need 8 cents but i only get 1 nickel and 2 pennies. she said because it rounds down the last penny.

public static void main(String args[])
{
float spent, tendered;
int dollars,quarters, dimes, nickels, pennies,change;

Scanner keyboard = new Scanner(System.in);

System.out.println("Bill Total");
spent = keyboard.nextFloat( );
System.out.println("Tendered.");
tendered = keyboard.nextFloat( );

change = (int) ((tendered - spent)*100);


dollars = (change/100);
change = change%100;
quarters = (change/25);
change = change%25;
dimes = (change/10);
change = change%10;
nickels = (change/5);
change = change%5;
pennies = (change);

System.out.println(dollars + " dollars");

System.out.println(quarters + " quarters");

System.out.println(dimes + " dimes");

System.out.println(nickels + " nickels");

System.out.println(pennies + " pennies");
}//end main
}//end class

Is this what your asking for? thanks for replying!

Bill Total
.92
Tendered.
1
0 dollars
0 quarters
0 dimes
1 nickels
2 pennies

What do you mean? Convert to cents before I put it through the this:

dollars = (change/100);
change = change%100;
quarters = (change/25);
change = change%25;
dimes = (change/10);
change = change%10;
nickels = (change/5);
change = change%5;

And how would I go about that if I'm wrong?

i think that its done here:
change = (int) ((tendered - spent)*100);

where whats left is converted to pennies

i think this is what you mean if not it works

        System.out.println(pennies + " pennies");
    }//end main
}//end class

my out put is this :

Bill Total
.92
Tendered.
1


0 dollars
0 quarters
0 dimes
1 nickels
3 pennies
