Q33

Consider the unsigned 8-bit fixed point binary number representation, below,

$$b_7 \: \: b_6 \: \: b_5 \: \: b_4 \: \: b_3 \: \: \cdot b_2 \: \: b_1 \: \: b_0$$

where the position of the primary point is between $b_3$ and $b_2$ . Assume $b_7$ is the most significant bit. Some of the decimal numbers listed below cannot be represented exactly in the above representation: Which one of the following statements is true? None of $i, ii, iii, iv$ can be exactly represented Only $ii$ cannot be exactly represented Only $iii$ and $iv$ cannot be exactly represented Only $i$ and $ii$ cannot be exactly represented
