Expand description

A wrapper for `f64`, which guarantees that the inner value is finite and thus implements `Eq`, `Hash` and `Ord`.

## Implementations

source

### impl Float

source

#### pub fn new(v: f64) -> Self

Construct a new `Float`.

source

#### pub fn get(self) -> f64

Returns the wrapped float.

## Trait Implementations

source

### impl Clone for Float

source

#### fn clone(&self) -> Float

Returns a copy of the value. Read more

1.0.0 · source

source

### impl Debug for Float

source

#### fn fmt(&self, f: &mut Formatter<'_>) -> Result

source

### impl Hash for Float

source

#### fn hash<H: Hasher>(&self, state: &mut H)

#### fn hash_slice<H>(data: &[Self], state: &mut H) where
H: Hasher,

source

### impl Ord for Float

Ordering comparison In order to be able to use `Float` as a mapping key, NaN floating values wrapped in `Float` are equals to each other and are less then any other floating value. It is not the case for underlying `f64` values itself. See the `PartialEq` implementation.

source

### impl PartialEq<Float> for Float

Partial equality comparison In order to be able to use `Number` as a mapping key, NaN floating values wrapped in `Float` are equals to each other. It is not the case for underlying `f64` values itself.

source

### impl PartialOrd<Float> for Float

Partial ordering comparison In order to be able to use `Number` as a mapping key, NaN floating values wrapped in `Number` are equals to each other and are less then any other floating value. It is not the case for the underlying `f64` values themselves.

    use ron::value::Number;
    assert!(Number::new(std::f64::NAN) < Number::new(std::f64::NEG_INFINITY));
    assert_eq!(Number::new(std::f64::NAN), Number::new(std::f64::NAN));
