Clemson University -- CPSC 231 -- Fall 2010 -- Study Guide for Final Exam
The final is cumulative as defined by previous study guides along with
additional material on floating-point identified below.
Approximate weights:
20% - Exam 1 material
20% - Exam 2 material
20% - Exam 3 material
35% - Exam 4/5 material
5% - floating point
1. Be able to define and discuss these terms:
binary fraction scaled numbers (fixed-point numbers)
floating point exponent
fraction hidden bit
significand bias notation (e.g., excess-127)
rounding cancellation of approx. equal numbers
flt. pt. addition flt. pt. multiplication
2. Be able to explain why computations with real numbers (i.e., floating
point) can sometimes experience errors. Why does the cancellation of
approximately equal numbers tend to magnify any representation and/or
roundoff errors?
