Study Notes
Integer Overflow
- An integer larger than 15 cannot be stored in a 4-bit memory location.
- Overflow occurs when trying to exceed the maximum limit of a specific bit representation.
Sign-and-Magnitude Representation
- Divides the range for unsigned integers (0 to 2^n − 1) into two equal sub-ranges: positive and negative integers.
- Positive integers are represented in the first half, while negative integers occupy the second half.
Bit Significance
- The leftmost bit (most significant bit) indicates the sign of the integer.
- A 0 signifies a positive integer.
- A 1 signifies a negative integer.
Example of Storing +28
- Convert +28 to 7-bit binary representation.
- Set the leftmost bit to 0 to denote a positive integer.
- Store the resulting 8-bit number.
Example of Storing -28
- Convert -28 to 7-bit binary representation.
- Set the leftmost bit to 1 to denote a negative integer.
- Store the resulting 8-bit number.
