2. Let us consider the following toy model of the IEEE double precision floating-point format. This toy model makes it simpler to demonstrate how addition and multiplication of floating- point numbers work. The sequence of 8 bits Co bi b2 b3 b4 ai 02 03 sign part exponent part mantissa part represents a number =.2e where o, , e are determined as follows: o E i if co= 0, 1 -1 if co = 1, = (b1b2b3b4)2 If 1
