Expand description

Enables evaluation of the principal and secondary branches of the Lambert W function on the types that implement this trait.

Required Associated Types§

Source

type Output

👎Deprecated since 1.1.0: use the functions directly or create your own trait, the lambert_w crate is not the place for making such API decisions for others.

The type returned by the Lambert W functions when acting on a value of type Self.

Required Methods§

Source

fn lambert_w0(self) -> Self::Output

👎Deprecated since 1.1.0: use the functions directly or create your own trait, the lambert_w crate is not the place for making such API decisions for others.

The principal branch of the Lambert W function.

Source

fn lambert_wm1(self) -> Self::Output

The secondary branch of the Lambert W function.

Implementations on Foreign Types§

impl LambertW for f32

Source§

fn lambert_w0(self) -> Self::Output

👎Deprecated since 1.1.0: use the functions directly or create your own trait, the lambert_w crate is not the place for making such API decisions for others.

The principal branch of the Lambert W function.

Evaluated with the approximation with 24-bits of accuracy from the paper, but on 32-bit floats.

Arguments smaller than -1/e (≈ -0.36787944) result in NAN.

Delegates to the lambert_w0f function.

fn lambert_wm1(self) -> Self::Output

👎Deprecated since 1.1.0: use the functions directly or create your own trait, the lambert_w crate is not the place for making such API decisions for others.

The secondary branch of the Lambert W function.

Evaluated with the approximation with 24-bits of accuracy from the paper, but on 32-bit floats.

Arguments smaller than -1/e (≈ -0.36787944) or larger than 0 result in NAN.

Delegates to the lambert_wm1f function.
