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

to $$f15=0xFFFFFFFF$ and $ f$16$ to $$f31=00.$ 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 $$f4,$$$f8,$$$f12,$ #$$f8=0xBFDFFFF$ and $$f12=0xC02FFFFF$

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

Write the resultant registers in hexadecimal.

mul.d $$f16,$$$f20,$$$f24,$ #$$f20=0$ABC$30000$ and $$f24=073DD0000$
