Struct Scalar 

pub struct Scalar(/* private fields */);

A 64-bit float that implements Eq, Ord and Hash.

Panics if it’s NaN during any of those operations.

Implementations

impl Scalar

pub const ZERO: Self

The scalar containing 0.0.

pub const ONE: Self

The scalar containing 1.0.

pub const INFINITY: Self

The scalar containing f64::INFINITY.

pub const fn new(x: f64) -> Self

Creates a Scalar with the given value.

If the value is NaN, then it is set to 0.0 in the result.

pub const fn get(self) -> f64

Gets the value of this Scalar.
