I’m trying to port one of my crates with no dependencies to work on no-std targets. I’ve managed to port everything, and I even found out that the
powi() methods in floats are unstable (why?).
But I cannot figure out how to use
acos() methods in f32/f64. I see they use unsafe intrinsics, but I don’t really understand why. I’m guessing they require allocation. Can they be replaced by other implementations?
Thanks in advance!
