A trait for real-valued floating point types

Required Methods

fn epsilon() -> Self

Returns the machine epsilon (the difference between 1.0 and the least value greater than 1.0)

fn exp(self) -> Self

Exponential function (e^x)

fn ln(self) -> Self

Natural logarithm (ln(x))

fn log10(self) -> Self

Base-10 logarithm

fn log2(self) -> Self

Base-2 logarithm

fn sin(self) -> Self

Sine function

fn cos(self) -> Self

Cosine function

fn tan(self) -> Self

Tangent function

fn sinh(self) -> Self

Hyperbolic sine

fn cosh(self) -> Self

Hyperbolic cosine

fn tanh(self) -> Self

Hyperbolic tangent

fn asin(self) -> Self

Inverse sine

fn acos(self) -> Self

Inverse cosine

fn atan(self) -> Self

Inverse tangent

fn atan2(self, other: Self) -> Self

Inverse tangent of y/x with correct quadrant

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

Power function

fn powi(self, n: i32) -> Self

Integer power function

fn factorial(self) -> Self

Factorial function (approximation for non-integers)

Dyn Compatibility

This trait is not dyn compatible.

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