Fuzzy logic and truth values

Truth Values that are between 0 and 1 indicate varying degrees of truth. For instance, the truth value 0.8 can be assigned to the statement "Bob is happy," because Bob is happy most of the time, and the truth value 0.4 can be assigned to the statement "Max is happy, "because Max is happy slightly less than half the time. Th
