$[10]$ An $8-$bit microcontroller is performing arithmetic using a signed $5\mathrm{.}3$ fixed point format $($that

is$,2s$ complement, $5$ bits for the whole part, and $3$ bits for the fractional part$).$ Show how the

following computations can be done on the system:

a$.6\mathrm{.}750+3\mathrm{.}125$

b$.1\mathrm{.}250-4\mathrm{.}500$

$[10]$ Consider the fixed point format from Question $2.$ What are the maximum and minimum

values that can be represented in this format? How many total values can be represented in this

format, and in what increments?

$[10]$ Convert the following to$/$from floating point. Show all work for credit$).$

a$.-3\mathrm{.}25$ to double precision floating point, written in hexadecimal

b$.0100001000101000000000000000000$ from single precision FP to decimal
