This is an excellent question, thank you. I answered it correctly because for years I cannot find the answer to the following question: why would anyone ever consider casually using float data type? I understand that there might be some specific scenarios where the inaccuracy of calculations are not important and the range of the numbers is huge, but using float for no good reason is astonishingly bad not to say plain silly. The query in Qotd is one fine example demonstrating this point.
