WebMar 29, 2024 · I see this line: "The math/rand package now automatically seeds the global random number generator (used by top-level functions like Float64 and Int) with a random value", so the confusion is still there for me because it doesn't seem to be doing this. I assume "top level functions" are the functions in the rand package (not the methods)?
