(a) State the steps necessary to carry out floating-point subtraction, including special cases. Assume that the numbers are initially in normalized form and the final result should be in normalized form.
(b) Subtract the following (fractions are in 2’s complement): 

(1.0111 x 2^-3) - (1.0101 3 2^-5)

(c) Write a Verilog description of the system. Fractions are 5 bits including sign, and exponents are 4 bits including sign.
