Problem 1: (see example-1 in page-5)

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
