Answer #1

binary representation of 35.625:

35 binary is 100011

0.625 binary is 0.101

35.625 = 100011.101

35.625 = 100011.101
Normalizing binary until one non zero is left on the left
100011.101 x 2^0
1000.11101 x 2^2
exponent=2
1000.11101

2+(2^8-1)-1 = (2 +127)
   = 129

129 in binary = 10000001 (exponent)
1000.11101000000000000000
100011101000000000000000 (normalized)

Binary representation of 36.625 in IEEE 754 is
0-10000001 -100011101000000000000000

What is the 16-bit binary representation (in hexadecimal using lower-case letters, e.g., 0x39ab) of -13 1/4 (base 10) when represented as an IEEE 16-bit floating-point number? The IEEE 16-bit floating-point representation uses formulae consistent with those for the 32bit single-precision representation, except for using 5 bits for the exponent (instead of 8 in the case of the 32-bit representation) and a bias of 15.
