We have two types of floats, there is a Pi of both precision levels. I don't think it's anything more than that. You should be able to cast between the two, but that's it I guess. Rust tries to give explicit control over such things.
There is a Float trait (might have been renamed) if you want to use generics. -Manish Goregaokar On Sun, Jan 4, 2015 at 3:07 PM, Pim Schellart <p.schell...@gmail.com> wrote: > Dear Rust Developers, > > here is another ignorant question so feel free to ignore. > When reading the guide I came across "std::f64::consts::PI” for pi.
