8) The floating-point format to be used in this problem is an 8-bit IEEE 754 normalized format with 1 sign bit, 4 exponent bits, and 3 mantissa bits. It is identical to the 32-bit and 64-bit formats in terms of the meaning of fields and special encodings. The exponent field employs an excess-7coding. The bit fields in a number are (sign, exponent, mantissa). Assume that we use unbiased rounding to the nearest even specified in the IEEE floating point standard (b) Perform the computation 1.011 two + 0.0011011 two showing the correct state of the guard round and sticky bits. There are three mantissa bits (c) Decode the following 8-bit IEEE number into their decimal value: 1 1010 101 (d) Decide which number in the following pairs are greater in value (the numbers are in 8-bit IEEE754 format): 0 0100 100 and 0 0100 111
