I remember when I was in grad school, I was out with drinks with a bunch of students from the biology department. One of them was talking about finishing up a paper to submit to the FDA on a drug she was testing. She called the FDA "the department of legalized rounding". Another author on her paper was proposing that they could round ".445" to ".45" and then to ".5" so that they could be above a threshold to go on to the next phase. She was horrified, but they were going through the regulations because it wasn't clear that it was prohibited.
