FixedPointReals: Does this work, in the C language, for the Q$16\mathrm{.}16$ format: $"$Q$16$ x $=3\mathrm{.}7$; $"?$

a$.$ Nope, the fractional part would be truncated to zero, the whole part would be copied into the fractional part of the Q$16\mathrm{.}16$ number.

b$.$ Nope, number is too big.

c$.$ Yes of course.

$10.[3$ pts$]($checkmark a$,$ b or c $-$ only one choice$)$:

FixedPointReals: What is the underlying C language data type of the Q$16.$Q$16$ format?

a$.$ signed integer $16$ bit

b$.$ signed integer $32$ bit

c$.$ signed integer $64$ bit

FixedPointReals: When subtracting two different $Q$ format numbers, what do you need to do first? i$.$e$.$ first number is $Q3$ and second number is Q$5$

a$.$ Multiply the second number by $2^2,$ then subtract.

b$.$ Multiply the first number by $2^2,$ then subtract.

c$.$ Nothing to do$!$

FixedPointReals: When multiplying two different $Q$ formats together, what is the resulting $Q$ format? i$.$e$.$ first number is Q$4$ and second number is Q$3$

a$.$ Q$4$

b$.$ Q$6$

c$.$ Q$7$
