I stopped using floats 30 years ago when I learned what rounding errors can do if you only deal with big enough numbers of items to tally. My employer turned around 25M a year, and it had to add up to the cent for the audits.
The physics starts to glitch out, or at least used to, until it got upgraded to doubles. I also use doubles for my game engine, as well as (optionally) limiting pixel-precise things within int.max and int.min.
The game, including worldgen, will still bug out at longer distances - the issues were reduced and a world limit was added to prevent you going too far, and IIRC past a certain point the world turns into non-stop ocean, but I’m pretty sure if you bypass those limits you’ll encounter chunks that outright fail to generate.
Fun fact: This is actually called the Salami Shaving Scam. Basically, shave off tiny pieces of a bunch of large chunks, and eventually you’ll have a massive amount. Like taking a single slice of salami from every sausage that is sold.

And KSP (rocket exploding game) had ten years worth of floating point errors.
Like Minecraft has, too. Just go on a long, long walk in one direction.
What happens?

int.maxandint.min.Does the world repeat after a set point?
Technically yes, and with tile layers, you can even set them repeating on a shorter area.
All kinds of weird things. There is a video explaining the details, and you’ve got to be far, far out.
Used to*, it was fixed in some version or another, where the procgen no longer evaluated how far you were from the origin
OK, I have not played it for AGES. Nice to see something like that fixed, as it was a bit system-inherent.

I’ll have to look it up after work. Sounds interesting.
There’s a good documentary about this.
