Store $xx$ in an $8-$bit memory location using unsigned representation? Show your work?

$xx=(???{)}_2$

Store $-xx$ in an $8-$bit memory location using sign$-$and$-$magnitude representation? Show

your work?

$-xx=(???{)}_2$

Store $-xx$ in an $8-$bit memory location using two's complement representation? Show

your work?

$-xx=(???{)}_2$

Where $xx=$ the last $2$ digits of your student number. Example $-xx=-76.$ If you have

one$/$two digits $0$ s$,$ use $5/55$ instead of zeros digits X$5/5$X$/55.$

Using floating$-$point representation $($IEEE$\_127)($single precision$),$ show the process how

$(-xx.xx)$ is represented?

Where $xx.xx=$ the last $2$ digits of your student number. Example $-xx.xx=-76\mathrm{.}76($no

more than $4$ digits in the fractional parts$)$

The number $(47802$D$58){?}_{16}$ is stored in floating$-$point representation $($IEEE$\_127).$ Show

the process to retrieve the original decimal number?

Hint: $1)$ convert hexadecimal to binary

use IEEE standards

Use the last digit of your student number as X$-$bit memory location in two's complement.

a$)$ How many different patterns $($symbols$)$ can be represented using $x$ bits?

b$)$ show the range for all numbers that can be represented $($minimum and maximum

values$)?$

c$)$ Show the binary representation of the first two numbers and the last two numbers?

d$)$ Discuss when an overflow would happen?

If $x2,$ use $x=5.$
