Chapter 1, Problem 36CRP

a.

Explanation of Solution

Decode 01011001 using the floating point format described in figure 1.24:

The rules of the floating format is,

  • The high order bit of the binary number is the sign bit. 0 is assigned as positive and 1 is assigned as negative.
  • The four bits from the right are assigned as mantissa field.
  • The remaining three bits represent the exponential field that is shown in the below table.
Bit patternvalue
1113
1102
1011
1000
0111
1012
0013
0004
  • Apply the above rules to the bit pattern 01011001.
  • The mantissa field of the given binary number is .1001, shift 1 bit to the left of the decimal point then the exponential field 001 represents 1 by follow the above table.. the number becomes 1.001
  • Convert the number 1 into base ten representation
