Trait Float

pub trait Float:
    Sized
    + Float
    + Lapack
    + ScalarOperand {
    // Required methods
    fn half() -> Self;
    fn total_cmp(&self, other: &Self) -> Ordering;

    // Provided method
    fn sign(self) -> Self { ... }
}

Required Methods

fn half() -> Self

fn total_cmp(&self, other: &Self) -> Ordering

total_cmp is not implemented in num_traits, so implement it here.

Provided Methods

fn sign(self) -> Self

A more conventional sign function, because the built-in signum treats signed zeros as positive and negative: https://github.com/rust-lang/rust/issues/57543

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
