Question: A computer uses 8-bit for FLP (1 bit for sign, 4 bit for exponent with excess-7 rep. (see table below), rest for magnitude). Assume 0000

A computer uses 8-bit for FLP (1 bit for sign, 4 bit for exponent with excess-7 rep. (see table below), rest for magnitude). Assume 0000 and 1111 in exponent field are reserved for denormalization.

Decimal	0	1	2	3	4	5	6	7
Unsigned	0000	0001	0010	0011	0100	0101	0110	0111
Excess-7	Reserved	-6	-5	-4	-3	-2	-1	0

Decimal	8	9	10	11	12	13	14	15
Unsigned	1000	1001	1010	1011	1100	1101	1110	1111
Excess-7	1	2	3	4	5	6	7	reserved

a. What is 11000000?

1000

000

Answer: - 1.0 * 2 ^ 1 = - 2

b. How 1 will be represented?

Answer:

c. What is the smallest fraction in this representation? (normalized)

min +ve

d. What is the largest number?

Largest

e. What is the second largest number?

second largest

f. Show that 240 -5 = 240 in this representation.
