It's the first result for "floating point site" on Google. Sure the domain itself is impossible to remember, but you don't have to remember the actual number, just what it stands for.
Remember filter bubble. My first result is not your first result. (although in this case it happens to be, but we both probably search a lot on programming)
Also did it in an InPrivate window to confirm, which is still somewhat targeted but far less so than on my actual account. It's still first.
And, at the end of the day, even if there's a filter bubble and it's the reason I see it first, then so what? The people looking for this site are likely going to fit into the same set of targeted demographics as you and me and most people on this site. So unless you also want to cater to 65-year old retirees that don't care about computer science and what floating numbers are, then why does the filter bubble even matter?
