Thread: number turning negative during calculation why???

so here is my calculation and when total equals 397,683 the numbers start turning negative....why at that number and why at all? it works fine up to 397,682

long days, hours, minutes, seconds;
 
				days = (long) (total / 86400);
				System.out.println("" + days);
				total = total - (days * 86400);  
				System.out.println("" + total);
				hours = (long) (total / 3600);
				System.out.println("" + hours);
				total =  total - (hours * 3600);
				System.out.println("" + total);
				minutes =  (long) (total / 60);
				System.out.println("" + minutes);
				total = total - (minutes * 60);
				System.out.println("" + total);
				seconds = (long) total;
				System.out.println("" + seconds);
 
 
 
				totalTime.setText("" + days + "d:" + hours + "h:" + minutes + "m:" + seconds + "s");

-24855
-7096.0
-1
-3496.0
-58
-16.0

thats what the println display when i do 397683

}

everything works great except this part where im trying to change the seconds into days, hours, minutes, seconds..if you run it and put 397682 in the troop field and 0 in the accel field and hit calculate the time at the bottom calculates but if you use 397683 the time comes out to be negative numbers or maybe its another part of my code thats messing with it?

also thank you for taking the time to reply its much appreciated

ahhhh found it i had troopnum as an int and it couldnt hold that big of a number cant believe i missed this thanks a lot
