Trait Float 

pub trait Float:
    Sealed
    + Copy
    + Add<Output = Self>
    + Sub<Output = Self>
    + Mul<Output = Self>
    + Div<Output = Self> {

    // Required methods
    fn from_f32(v: f32) -> Self;
    fn from_f64(v: f64) -> Self;
    fn to_f32(self) -> f32;
    fn to_f64(self) -> f64;
    fn exp(self) -> Self;
    fn log10(self) -> Self;
    fn powf(self, exp: Self) -> Self;
}

Math on f32 or f64 (gains, freqs, coefficients — not necessarily samples).

Prefer Sample for AudioBuffer<S> and similar buffer bounds.

Required Associated Constants

const IS_F64: bool

true for f64. Sealed, so equal IS_F64 means same type.

Required Methods

fn from_f32(v: f32) -> Self

Widen f32 → this precision (identity on f32).

fn from_f64(v: f64) -> Self

Narrow f64 → this precision. Debug-asserts non-NaN on f32 (NaN in the audio path is always a bug). Release keeps NaN via as.

fn to_f32(self) -> f32

Narrow to f32 (same NaN debug-assert as Self::from_f64).

fn to_f64(self) -> f64

Widen to f64.

fn exp(self) -> Self

fn log10(self) -> Self

fn powf(self, exp: Self) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
