I just rolled back an edit on my question that added . The person who added the tag gave as reason that some answers are in Java. I personally think that if the answers are in Java this does not mean that the question should be tagged Java - and so I removed the tag.

Was I right?

    Usually adding a tag based on the answers is correct, but in this case you made the right call. Mar 15, 2013 at 21:35

    If that question is based on pure math, I believe its off topic for SO. Mar 15, 2013 at 21:38
  • @AbZy well it's quite a common problem in some areas (mostly games), with a specific function made for it in most programming languages (atan2). I think 27000+ views can't be ignored either.

You were completely right on this. This has nothing to do with Java in particular. It is soley in general math, applicable for all languages.


Tags are added to the question because the topic of the question, not because what said in answers.
Suppose there is a Drupal question asking which module should be used to achieve a specific task; different users would probably suggest different modules, but that doesn't mean the question should have a tag for each of the suggested modules, when those tags exists. (This example is for a possible question on Drupal Answers.)
