In my previous post, I explained that floating point numbers are a leaky abstraction. Often you can pretend that they are mathematical real numbers, but sometimes you cannot. This post peels back the abstraction and explains exactly what a floating point number is. (Technically, this post describes an IEEE 754 double precision floating point number, by far the most common kind of floating point number in practice.)
