Represent the following value using 8-bit fixed-point notation. Use 4 bits for the integral portion and 4 bits for the fractional portion. Fill in the blanks below with 4 bits in each.

5.625

Answer: ???

---------------------------------------------------------------------------

A simplified IEEE-754 floating-point representation uses 1 bit for the sign, 5 bits for the exponent, and 4 bits for the fractional mantissa. Here is a binary value in that representation:

0 01011 1010

The 5-bit exponent uses excess-15 for its representation.

Convert this to decimal (base 10). Please use at least 3 decimal places. Don't round the integer portion. Remember the sign if the number is negative!

Answer?????

---------------------------------------------------------------------------------------------------------------

For this problem we will use a hypothetical floating-point representation that is similar to IEEE-754. It uses 12 bits total, consisting of 1 sign bit, 5 exponent bits, and 6 mantissa bits.

Convert -14.125 to this format. Write the three portions of the number below as binary strings using the appropriate number of bits.

Sign (1 bit): ?

Exponent (5 bits): ?

Mantissa (6 bits): ?
