A numeric type supported by ha-ndarray

Required Associated Constants

const ZERO: Self

The zero value of this data type.

const ONE: Self

The one value of this data type.

Required Associated Types

type Abs: Number

The absolute value type of this Number.

Required Methods

fn abs(self) -> Self::Abs

Construct an instance of this type from a f64.

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

Add two instances of this type.

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

Divide two instances of this type.

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

Multiply two instances of this type.

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

Subtract two instances of this type.

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

Raise this value to the power of the given exponent.

Dyn Compatibility

This trait is not dyn compatible.

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