Question $16$

Convert the decimal number $-4\mathrm{.}375$ to a floating$-$point number expressed in the $14-$bit simple model given in your

textbook.

Note: in the $14-$bit simple model, the left$-$most bit is the sign, followed by $5$ bits for the exponent, followed by $8$ bits for the

mantissa $($There are no implied bits$).$ The exponent is in Excess $15$ notation.

Question $17$

Consider the following code word coded using the Hamming algorithm presented in your text with even parity:

$100101011100$

Indicate which bit is in error. If none, indicate so $($enter None in the textbox$).$

Question $18$

The binary string $11001111001110$ is a floating$-$point number expressed using the $14-$bit simple model given in your

text. What is its decimal equivalent?

Note: in the $14-$bit simple model, the left$-$most bit is the sign bit, followed by $5$ bits for the exponent, followed by $8$ bits for the

mantissa $($There are no implied bits$).$ The exponent is in Excess $15$ notation.
