WebApr 4, 2024 · For example, an 8-bit computer is capable of storing unsigned integers ranging from 0–255. Any operation that generates an output which is less than 0 will result in an underflow. WebTo negate a signed 8-bit value (ranging from -128 to +127), toggle all the bits, then add 1. A error has occurred if a carry is generated — the initial value was out of range (a negated -128 can’t produce +128). Negating a 16-bit value is similar. Flip the bits of both bytes. Add 1 to the LSB. If a carry is generated, add 1 to the MSB.
