Can this be explained in context of numbers which are out of integer
range ?
This can be explained by integer storage in computer and overflow due to
limited range.
Remember that in computer negative integer is stored as the two's
complement, ie. -x = (~x)+1.
(http://en.wikipedia.org/wiki/2%27s_complement)
Apply this to 0x80000000, we get: -0x80000000 = 0x7fffffff+1 =
0x80000000.
Note in the last addition, overlap occurs (from 2^31-1 to -2^32)
