A minor difficulty is in dealing with negative numbers, since they have a leading one, and they occur in descending order, but this can be overcome without requiring floating-point operations to perform comparisons (see Problem 2.47). Practice Problem 2.25: Consider a 5-bit floating-point representation based on the IEEE floating-point format, with one sign bit, ¾), and two fraction bits (Ò ¾). The exponent bias is ¾¾ ½ ½ ½. two exponent bits ( The table below enumerates the entire nonnegative range for this 5-bit floating-point representation. Fill in the blank table entries using the following directions: : The value represented by considering the exponent field to be an unsigned integer. : The value of the exponent after biasing. : The value of the fraction. Å Î : The value of the significand. : The numeric value represented. Express the values of , Å and Î as fractions of the form Ü . You need not fill in entries marked “—”.
