$(6$ points, $3$ each$)$ Consider a $32-$bit number stored in a byte$-$addressable memory as

shown in the table below $($note that the value is written in hex format$)$:

a$.$ If the machine is little endian and uses $2\text{'}$s complement representation for

integers, give the decimal representation of the $32-$bit integer that starts at

address $100.$

b$.$ If the machine is big endian and the number is an IEEE single precision

floating point value, give the decimal equivalent. Note the following:

When converting the binary significand to its base $10$ equivalent, you

only need to use the first $8$ bits $($not all $23)$

The final answer should be written as a simple real number $($i$.$e$.,$ not

in exponential format$),$ with the fractional component rounded to $2$

decimal places $($e$.$g$.,126\mathrm{.}46$ or $-9768\mathrm{.}83)$
