Min integer value in 32bit representation

[Rahul Patel]

I have simple question related to representation of negative number.
What "valid" minimum integer value can hold by 32bit signed datatype?
Is it -2147483648 (0x80000000) or -2147483647 (0x80000001)? If we do
2's compliment in 32bit then both represent same value.

The minimal number in two's complement notation is 0x80000000= -2147483648. The interesting fact about this number is that it is equal to its own complement, i.e. inverting all bits results in 0x7FFFFFFF and adding 1 yields 0x80000000, which is equal to the original number.
