Everything ends up in your database as bytes. You can say everything is a number. It's just naming. Whether it's sane to do basic math operations on them is loosely correlated with whether user sees that number as an integer on his screen. Most bugs are stupid and should be obvious. They happen. You can look at your old code and say WTF, so judging decisions in somebody's else complex system without having any idea about requirements and constraints seems pointless.
