There is no difference, not even an infinitesimally small one. 1 and 0.999... represent the exact same number.
Well, technically “infinitesimally small” means zero sooooooooo
Edit: this is wrong
An infinitesimal is a non-zero number that is closer to zero than any real number. An infinitesimal is what would have to be between 0.999... and 1.
Wait what
I always thought infinitesimal was one of those fake words, like gazillion or something
It sounds like it should be, but it's actually a real (or, non-real, I suppose, in mathematical terms) thing! :)
