Trait FloatExt 

pub trait FloatExt {
    // Required methods
    fn ln(self) -> Self;
    fn sqrt(self) -> Self;
    fn cos(self) -> Self;
    fn exp(self) -> Self;
}

Floating-point math operations bridged across std / libm.

This trait provides a unified interface for mathematical functions that are usually available in the standard library but missing in core.

Examples

use vrd::FloatExt;

let n = 2.0f64;
let ln_n = n.ln();
let sqrt_n = n.sqrt();

Required Methods

fn ln(self) -> Self

Natural logarithm.

Examples

use vrd::FloatExt;
let n: f64 = std::f64::consts::E;
assert!((FloatExt::ln(n) - 1.0).abs() < 1e-12);

fn sqrt(self) -> Self

Square root.

Examples

use vrd::FloatExt;
assert!((FloatExt::sqrt(4.0_f64) - 2.0).abs() < 1e-12);

fn cos(self) -> Self

Cosine.

Examples

use vrd::FloatExt;
assert!(FloatExt::cos(0.0_f64) - 1.0 < 1e-12);

fn exp(self) -> Self

Exponential.

Examples

use vrd::FloatExt;
assert!((FloatExt::exp(0.0_f64) - 1.0).abs() < 1e-12);

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.
