7. 30 Points Convert the following base-2 numbers to base-10 : (a) 1011 0011, (b) 0.010 011, and (c) 111.101011 8. 20 Points For an 8-bit representation of integers, +79 can be represented as 0100 1111. Use 2's complement to find the 8-bit representation for -79. 9. 20+ 1025 25 80 Points In the past 32-bit single precision representation for a floating point number was common. In this representation, each value is stored in 4 bytes with 1 bit for the sign, 23 bits for the normalized mantissa, and 8 bits for the BIASED exponent. Given that the exponent cannot contain either all 1's or all zeros, determine a logical choice for the bias. Determine: (a) the machine epsilon, (b) the smallest positive representation, and (c) the largest positive representation
