In a hypothetical 6-bit floating point format (for positive numbers only), 3 leading bits are used for exponent (E, in 2s complement format) and 3 remaining bits for mantissa (M ), and the value is evaluated as 1.M 2E , answer the following questions:

(a) Find the decimal value of the expression 111101.

(b) Find the decimal value of the expression 011011.

(c) Determine the range of this format; i.e. ? N ?.

(d) Find the expression (representation) for decimal value 2.5.

(e) Find the expression (representation) for decimal value 0.39 (use simple truncation for bits exceeding the format field).
