The number 4294983648L in the binary system is: 100000000000000000011111111100000. This takes up 33 bits. An int can only hold 32 bits so we have a problem. Also one of those 32 bits is used to indicate whether the number is positive or negative. So only the last 31 bits can be stored for a positive number in an int. So only 0000000000000000011111111100000 gets put in the variable. That binary number in decimal form is 16352.
