For Questions $4$ and $5,$ consider all floating point registers have the following default values: $f$0$

to $f$15=0$xFFFFFFFF and $f$16$ to $f$31=0$x$0.$ Modifications in some register values are specified

for each of the subparts.

Question $4$: Show the steps to subtract the following double precision floating point numbers.

Write the resultant registers in hexadecimal.

sub.d $f$4,$ $f$8,$ $f$12$ # $f$8=0$xBFDFFFFF and $f$12=0$xC$02$FFFFF

Question $5$: Show the steps to subtract the following double precision floating point numbers.

Write the resultant registers in hexadecimal.

mul.d $f$16,$ $f$20,$ $f$24$ # $f$20=0$xABC$30000$ and $f$24=0$x$73$DD$0000$
