Please give me First and second answer. If you don't mind please check my 3rd question is this my question is right or wrong. Thanks

  1. Show how each of the following floating point values would be stored using IEEE-754 single precision (be sure to indicate the sign bit, the exponent, and the significand fields): (show your work)
    1. 12.5

  1. −1.5

  1. 0.75

  1. 26.625

  1. Show how each of the following floating point values would be stored using IEEE-754 double precision (be sure to indicate the sign bit, the exponent, and the significand fields): (show your work)
    1. 13.5

  1. −102.25

  1. 0.0078125

3.  Consider an unsigned fixed point decimal (Base10) representation with 8 digits, 5 to the left of the decimal point and 3 to the right. ( Have to fixed)

a.      What is the range of the expressible numbers?

                  Answer: [00000.000, 99999.999]

b.      What is the precision?

                  Answer: 0.001 the precision is the distance between successive numbers.

c.       What is the error? (Confused)

                  Answer: the error is ½ the precision. The error is 0.001/2 = 0.0005

However, it uses 30 bits. Among these bits, the most significant (i.e. the leftmost) bit is for the sign (same as IEEE 754), the following 7 bits are for the biased exponent with the bias as 63, and the rest are for the significand.

IEEE 754-2008 contains a half precision that is only 16 bits wide. The left most bit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and the mantissa is 10 bits long.

    In this question you will use the data type “bit32” introduced in Lab 2 (i.e. an unsigned int). We will use the IEEE 754 standard for floating point numbers, with 1 sign bit, 8 bits for the exponent, and 23 bits for the mantissa. For the following programming questions, place each function in a common file “fplib.c” for compiling and testing. You are not to use any C floating point data types (i.e., float, double). You can use the bitwise...
