a)Assuming that you are required to make an 8 bit floating point representation, where bit 7 is a sign bit, bits 4, 5, and 6 are the 3 bit exponent using excess-3 notation and bits 0, 1, 2, 3 represent a 4 bit mantissa using normalized notation. a) How would the number 2.25 be stored in the byte? b) What is the number that its binary representation is 11101010?

b)Assuming that you are required to make an 8 bit floating point representation, with a 3 bit exponent using excess-3 notation and a 4 bit mantissa using normalized notation. How many numbers can you represent between 2.5 and 3(including 2.5 and 3).
