Even when two values are not integers, e.g. literal strings, this convention is largely adopted. For example, strcmp returns -1, 0, or 1 according to the lexicographical order, and qsort expects the Comparisin function to return valuesaccording to this convention. This is because it is efficient to do the subtraction x - y resulting in the directionalsigns above. In sorting algorithms, the efficiency of Compariaon code is critical since it is one of the major factors of sorting performance. Sometimes, particularly in object-orientedprogramming, the Compqrison raises questions of datatypes and inheritance, equality and identity. It is often necessary to distinguish between: two objects with different datatypes both related to another datatype, e.g. an orange and a lemon, both being citrusfruit two different objects of the same type, e.g. two hands two objects being equal but distinct, e.g. two $10 banknotes two different references to the same object, e.g. two nicknames for the same person Sameness and difference can be relative or graduated as well as absolute, particularly in fuzzy logic, artificialintelligence, signal processing, lossy data compression and pattern recognition.
