Precisely defined limits are not the same as precisely defined values. I might precisely define the amount of entropy on a random value as being some formula based on the current temperature of my CPU. The formula is quite precise, but the value is only precisely known after I take the temperature... and even then it probably doesn't serve me to know it explicitly unless I'm verifying results. If I then take that random value and use it to make other decisions then the end result isn't exactly precise. Taking this to a world of expansion... everything we do as humans probably comes down to a precise formula, all our thoughts and all our actions based on those thoughts. But what isn't so precise, is knowing all the variables that impose themselves upon the decision making process at the atomic/sub-atomic level. As for how this affects the aspect ratio of an image... it doesn't really, but the person who said that "You can't really be 'approximate' when coding" didn't exactly confine it to the question about aspect ratio and an image.
