Would you mind expanding the `ULP` acronym you’re using: if it’s so fundamental to understanding this, I’d like to know what it is.

- tux3 6y agoMy apology, ULP stands for "Unit in the Last Place". The simple explanation is that an ULP is defined as the difference between two consecutive floating point numbers, which means it isn't a fixed value. Another "intuitive" explanation, is that if you increment the binary representation of a float, the difference between the two numbers is 1 ULP. (I'd explain more, but I have to run to a meeting!
