3.  It is not represented by
85.236
56620.856647783
 It is represented by
1.101101*2^6
0.001011011*2^9 Exponent
Both of this in
Normalized form

5.  Sign
 Exponent
 Mantissa
 Sign is
101110110First bit is the sign bit in Binary (0+ve) (1-ve)
 Exponent is derived from 2 formulas
 Mantissa is also derived from this 2 formulas
Single Precision Double Precision
(1.N)2E-
127

should be
made to get
E
N is the Mantissa part

12.  Addition
 Subtraction
 Multiplication
 Division

13. Add (1.1100*24) + (1.100*22)
Sol:- Make the Exponent equal like
(1.1100*24) + (0.01100*24)
Now ADD the Digit
1.1100 *24
+ 0.0110 *24
10.0010 *24
Now Normalize the result like:
10.0010*24 0.100010 *26 (Ans)

14. Add (1.1100*24) + (1.100*22)
Sol:- Make the Exponent equal like
(1.1100*24) - (0.01100*24)
Now ADD the Digit
1.1100 *24
- 0.0110 *24
1.0110 *24
Now Normalize the result like:
1.0110*24 (Ans)
