Explanation:
Conversion to Two's Complement
The 2's complement system is commonly used for signed integer representation on computers. The 2's complement operation is done by inverting the binary digits of an integer and then adding one.
For the purpose of explanation lets make use of a negative number for clarity. In this case lets use -923.
Note that the use of 32bits for this question is objective, you can use a range of bits for this operation. this question can go as low as 16bits and as high as 64bits depending on application and specification.
For Example:
we have -923, and want to represent it in 2's complement, you take the binary representation of positive 923:
0000 0000 0000 0000 0000 0011 1001 1011
Invert the digits.
1111 1111 1111 1111 1111 1100 0110 0100
And add one.
1111 1111 1111 1111 1111 1100 0110 0100 + 1
=
1111 1111 1111 1111 1111 1100 0110 0101
(The Binary 2's complement representation of -923)
