Assume a 32-bit floating point format with 7 bits for Exp and 24 bits for Frac. a. What is a bias for this format? b. Construct a table similar to one on Slide E14 or E15. Single precision numbers provide 6 or 7 significant decimal digits. If a result of some arithmetic operation is a larger number than the largest normalized number rightarrow floating point overflow. Double precision numbers provide 15 significant decimal digits. If a result of some arithmetic operation is non zero and smaller than the smallest deformalized number rightarrow underflow;
