    Corrections
    1:31:00- The answer should be 011.01.
    1:31:30 - The solution is ???? Must have copied it from another question! Should be:
    10101 011
    Mantissa is 1.0101
    Exponent is 3 (011)
    As it is a positive exponent, shift binary point 3 places to the right.
    Answer is 1010.1 or -5.5 (-8+2+0.5)
