Study Notes
Two's Complement Representation
- Converting a positive binary number into a negative binary number with equivalent negative value is done by using the two's complement operation.
- The purpose of using two's complement in computer science is to simplify the subtraction operation and to enable the representation of negative numbers.
Determining the Sign of a Binary Number
- In two's complement representation, the sign of a binary number is determined by the most significant bit (MSB).
- If the MSB is 0, the number is positive; if the MSB is 1, the number is negative.
Achieving Two's Complement
- The first step in achieving two's complement is to find the one's complement of the binary number.
- Then, add 1 to the result to get the two's complement.
Handling Overflow
- If overflow is not accounted for when performing two's complement, it can lead to incorrect results and errors.
- Therefore, it is essential to detect and handle overflow when performing two's complement operations.
