"(int) Math.ceil (double)" always returns 1, even if the value is greater than 1

I am creating an Android application and I need to calculate the speed of the device. I do this by taking the average of the speeds of the earlier locations. However, I need the speed to be km/h

like int

, so I use

(int)Math.ceil(speedAsDouble)

      

        
        
        
      

    

However, it is always equal 1

, even if speedAsDouble

equal 7.8825246

or 0.58178

.
This is the important part of the code:

// Create a variable for the speed
double speedAsDouble = 0d;

// Loop through the last points
for(int i = 0; i < lastPoints.size() - 1; i++)
{
    // Add the speed for the current point to the total speed
    speedAsDouble += (double)(lastPoints.get(i).distanceTo(lastPoints.get(i + 1)) / (lastPoints.get(i + 1).getTime() - lastPoints.get(i).getTime()));
}

// Divide the speed by the number of points
speedAsDouble /= (double)lastPoints.size();
// Convert the speed to km/h
speedAsDouble *= 3.6d;

// Log the speed
System.out.println("Speed: " + speedAsDouble);

      

        
        
        
      

    

Then I round the number and pass it to int as described above using

int speedAsInt = (int)Math.ceil(speedAsDouble)

      

        
        
        
      

    

and write down the number again with

System.out.println("Rounded speed: " + speedAsInt)

      

        
        
        
      

    

Here is part of the log:

05-17 12:00:42.605  24610-24610/package I/System.out﹕ Speed: 0.0

05-17 12:00:46.605  24610-24610/package I/System.out﹕ Rounded speed: 1

      

        
        
        
      

    

I spent a lot of time on this trying to use different types of variables and variables, but with no success.
