It was the same in the situation I was talking about; all numbers that would always be integers because of their nature (and in the data source they came from, they were integers, there was no way this could ever have been floating point, or that the values ever had any non-0 digits after the comma). And well, they probably weren't 'idiots' in the absolute sense, in fact I'm 100% sure that they are much smarter (and/or just plain better humans in other ways) than I am in many respects.

My point was that many researchers can only cobble together somewhat barely working software by taking snippets from their undergraduate textbooks (or googling/stack overflowing, for those under 40), and have no idea about many/most of the underlying principles. If only they would recognize that, and leave the software development to professionals, instead of treating it as an inconsequential implementation detail that is beneath them. Then again, if they did, they wouldn't have to pay me what they do to fix it up afterwards. So meh?
