<p>The interpretations of logical expressions found in most introductory textbooks are not suitable for use in software engineering applications because they do not deal with partial functions. More advanced papers and texts deal with partial functions in a variety of complex ways. This paper proposes a very simple change to the classic interpretation of predicate expressions, one that defines their value for all values of all variables, yet is almost identical to the standard definitions. It then illustrates the application of this interpretation in software documentation.</p>
