Final answer:
Without the specific bit patterns for the three-bit exponent field and four-bit significand provided in the question, only the method for converting these floating-point representations into decimal values can be explained. The exact decimal values cannot be determined.
Step-by-step explanation:
To determine the decimal values represented by given bit patterns with a three-bit exponent field and a four-bit significand, we follow the standard format for floating-point numbers. Generally, the floating-point representation is given by (-1)s × 1.f × 2(e - bias), where 's' is the sign bit, 'f' represents the significand, and 'e' represents the exponent field.
However, the question does not provide the explicit patterns that need to be evaluated, nor does it specify the inclusion of a sign bit or the bias used for the exponent field. Assuming a positive sign and a bias that is half the maximum value an exponent field can represent (which is 7 for three bits), a bias value of 3 might be used. Without the specific bit patterns, we can't compute the precise decimal values. Instead, we can only explain the method of converting bit patterns into decimal but cannot give a numerical answer.
