This post is spurred by this question. The question has received 4 answers, all of them saying something different from the other and there is deep disagreement between all the answerers and the commenters. The comments were getting out of control and I have locked it to prevent any more back and forths. But let's take this opportunity to step back and look at the whole situation, so that we can avoid such instances in the future.
On the face of it, the question seems innocent and extremely basic. It's almost the kind where you'd want to jump on it to answer first and ride the upvote train. But wait... as a few users pointed out, the question really doesn't make sense, because a transform of the kind that the OP asked (reading the question literally), doesn't exist!
What do we do in this case? Do we read into the OP's mind and answer what we think that they should've asked? This is what all the answerers did. What if you're reading incorrectly? It would then be a waste of time for the person who wrote the answer, the few others who read it, others who commented that it is incorrect, etc. All of this because of an ambiguously worded post.
We must remember that while we're a welcoming site and will gladly answer simple questions or help people struggling to understand concepts, the question must also be written correctly and completely. If this is not done, please do not hesitate to close the question until it has been improved. That is, in fact, the very essence of the close/reopen system at Stack Exchange.
In such cases in the future, I suggest that we withhold answers until the actual question has been clarified either through comments or via chat and the question has been updated with the correct info. This is critical, because again, we can't expect people to read through pages of comments to see that OP changed their mind.
I'd be interested to hear your thoughts on this particular question and dealing with such incidents in the future. Please, let's try to keep this discussion about the nature of the question, rather than the technical details of it.
