--Provide the Packed Decimal representation of the following decimal numbers:

          a)     -75                             b)     7657                         c)     -4327--

Convert the following hexadecimal numbers to floating-point format using single-precision IEEE 754 

       format. Convert your answer to hexadecimal format.

           a)     251D                       b)     -B26.9                      c)     -0.00A5 --

Is there a relationship between EBCDIC character representation of the decimal digits from 0 to 9 and their BCD representation? Explain.--Consider a hypothetical computer system. A two-byte memory space is used for a sign-and-magnitude representation of integers with BCD, and the sign is stored in MSB. What is the range of signed integers in base 10 that can be so represented? Explain.--

Convert the following binary numbers to floating-point format using single-precision IEEE 754 format. 

     Convert your answer to hexadecimal format. 

c)     -0.0101101Perform the calculation 97.685 + 0.97685 using the decimal floating point representation SEEMMMMM, where S is the sign (0 for "plus", 1 for "minus"), EE is the decimal exponent in excess-50 notation and MMMMM is the five-digit mantissa. Show all steps and explain the result.--

The following numbers are in IEEE 754 single-precision floating-point format. What decimal numbers 

        do they represent?

           a)     C3C2E000₁₆            b)     483C5400₁₆  

True or False: In ten's decimal complement, negative numbers are represented by themselves.   

True or False: In the IEEE 754 format, the exponents 0 and 255 are used to represent special values.
