1) What is the base-10 equivalent of:
a) 1010, a 4-bit two's complement number
b) 1111, a 4-bit one's complement number
c) FEC2FEFF hexadecimal (unsigned integer)
2) What are the differences between using single precision vs. double precision floating point numbers in how numbers (size, accuracy, etc.) can be represented?
3) Describe the conditions that have to be in place for an overflow to occur after an integer addition operation.
4) Add the following 16-bit 2's complement numbers (represented in Hex): 78EF + FAB8 and indicate whether or not there is a carry and/or an overflow generated. Also, if no overflow, give the result in base-10 format.
5) Add the following 16-bit 2's complement numbers (represented in Hex): 8FF9 + 82EF and indicate whether or not there is a carry and/or an overflow generated. Also, if no overflow, give the result in base-10 format.
6) If the term excess-128 notation is used in context of an exponent that is 8-bits in length, what is the range of the power that the exponent can represent?
7) Using the floating point format described in problem 5.19 of your text, convert the binary number -101011011010.101101001 to the floating point representation.
8) Using the floating point format described in problem 5.19 of your text, convert the floating point number represented by 2FFAEE50 to base 10 (decimal) representation.
9) Provide a hexadecimal ASCII conversion for the following text phrase: I like to watch TV at 8:30.
