Two's Complement Wrap-AroundIn this section, we give an example showing how temporary overflow in two's complement fixed-point causes no ill effects.
In 3-bit signed fixed-point arithmetic, the available numbers are as shown in Table 9.1.
Let's perform the sum , which gives a temporary overflow (, which wraps around to ), but a final result () which is in the allowed range :10.3
