Additional remarks
Binary representation of the value and its absolute value:
1. Whether the data is a positive value or a negative value depends on the value of the highest bit in the register. If
the highest bit in the register is 0, the data is a positive value. If the highest bit is 1, the data is a negative value.
2. You can convert the negative value into its absolute value with the instruction NEG.
