This was asked in the exam I have written today and confused me, I'd like to know if I did it correctly:
Convert the decimal $9.5$ to fixed-point arithmetic, with $5$ significant figures.
I took $9$ and converted it to binary first: $1001$
Now I took the significant figure $0.5$ and multiplied it with $2$:
$$0.5 \cdot 2 = 1.0$$
$$0 \cdot 2 = 0.0$$
$$0 \cdot 2 = 0$$
$$0 \cdot 2 = 0$$
$\Rightarrow$ $9.5$ in fixed-point arithmetic is $1001\ 10000$
Please tell me if it's correct, I did it exactly like this in the exam and I hope it's right because the exam was hard and this was one of the easy task but the zeroes made me feel unsure : /
