How would you represent positive and negative numbers in a computer?
In this approach, a number’s sign is represented with a sign bit: setting that bit (often the most significant bit) to 0 for a positive number or positive zero, and setting it to 1 for a negative number or negative zero. The remaining bits in the number indicate the magnitude (or absolute value).
What symbols are used to represent positive and negative numbers?
