20. (20 Points) We are creating a new 8 bit floating point binary number format. It will consist of a sign bit (positive, 1 negative), 3 bits for the exponent, and 4 bits for the mantissa. We will be using a 3 offset for the exponent. Assume there is a leading 1 (to the left of the decimal point) for the mantissa. This is the same TINFO 320 format we have been using. Convert A2 (hex) to floating point decimal format, show all work
