Question on my math

So in computer science we keep getting pounded with assignments and homework!!

And on one assignment its a parking garage program which asks you how long you parked (in minutes) then charges you 75 cents for each hour. i got that part but if you stay for part of an hour you have to pay for tha full hour. How would i do that? Im off by like 1 minute and have an infinite loop which freezes my computer.

All help is very much appreciated

Code :

---

import java.io.*;
public class Temp {
 
    public static void main(String[] args) throws IOException {
    	BufferedReader input= new BufferedReader(new InputStreamReader(System.in));
 
        int minutesstayed;
        System.out.println("Welcome to NO DENTS PARKING GARAGE");
        System.out.println();
        System.out.println("How long did you park for (in minutes)"); 
        minutesstayed=Integer.parseInt(input.readLine()); 
        int result=minutesstayed/60;
        double result2=result+0.75;
        double charge=0.75*(minutesstayed/60)+result2;
        for(result=1;result<=10;result2++)
 
        System.out.println("Your Parking Fee is:"+" "+charge);
 
 
    }  
}

Have you ever used the modulus operator? It returns the remainder of a division.

So...

Code :

---

int a = 4 % 2;
System.out.println(a)

---

Prints: 0

and...

Code :

---

int b = 12 % 7;
System.out.println(b);

---

Prints: 5

That is 12 / 7 = 1 with a remainder of 5

yeah ive used modulus. I didnt think i needed it. Where would i use it?

Code :

---

int minutes = Integer.parseInt(in.readLine());
int hours = minutes / 60;
if (minutes % 60 > 0)
    hours++;

---

If minutes modulo 60 is greater than zero, it adds another hour to the bill.

Convert the number of hours parked to a double, then use Math.ceil().

edit:

err, I just realized a flaw in this approach. Math.ceil() will still round up if you have 1.0 hrs (or some other "integer" hour value). Go with what literallyjer said :)
