Questions tagged [compare]

The analysis required to assess the differences and similarities between two or more entities.

This tag is used to classify a question as one dealing with the comparison of at least two entities. The essence of questions that are tagged should boil down to one of the following questions:

  1. How do I control when the compiler/interpreter thinks that two entities are equal? How do I control when the compiler/interpreter thinks that two entities are unequal?
  2. How do I control when the compiler/interpreter thinks that one entity is bigger than the other?
  3. How do I control when the compiler/interpreter thinks that one entity is smaller than the other?

Note that in some languages, it is possible to define asymmetric inequalities. That is, cases in which a<b does not mean that b<a. This is why in python, there exist separate functions for __gt__ (greater than) and __lt__ (less than), etc
