# Struct emath::range::Rangef

``````#[repr(C)]pub struct Rangef {
pub min: f32,
pub max: f32,
}``````
Expand description

Inclusive range of floats, i.e. `min..=max`, but more ergonomic than `RangeInclusive`.

## Fields§

§`min: f32`§`max: f32`

## Implementations§

source§

### impl Rangef

source

#### pub const EVERYTHING: Self = _

Infinite range that contains everything, from -∞ to +∞, inclusive.

source

#### pub const NOTHING: Self = _

The inverse of `Self::EVERYTHING`: stretches from positive infinity to negative infinity. Contains nothing.

source

source

source

source

#### pub fn span(self) -> f32

The length of the range, i.e. `max - min`.

source

#### pub fn center(self) -> f32

The center of the range

source

source

#### pub fn clamp(self, x: f32) -> f32

Equivalent to `x.clamp(min, max)`

source

#### pub fn as_positive(self) -> Self

Flip `min` and `max` if needed, so that `min <= max` after.

source

#### pub fn shrink(self, amnt: f32) -> Self

Shrink by this much on each side, keeping the center

source

#### pub fn expand(self, amnt: f32) -> Self

Expand by this much on each side, keeping the center

source

#### pub fn flip(self) -> Self

Flip the min and the max

source

#### pub fn intersection(self, other: Self) -> Self

The overlap of two ranges, i.e. the range that is contained by both.

If the ranges do not overlap, returns a range with `span() < 0.0`.

``````assert_eq!(Rangef::new(0.0, 10.0).intersection(Rangef::new(5.0, 15.0)), Rangef::new(5.0, 10.0));
assert_eq!(Rangef::new(0.0, 10.0).intersection(Rangef::new(10.0, 20.0)), Rangef::new(10.0, 10.0));
assert!(Rangef::new(0.0, 10.0).intersection(Rangef::new(20.0, 30.0)).span() < 0.0);``````
source

#### pub fn intersects(self, other: Self) -> bool

Do the two ranges intersect?

``````assert!(Rangef::new(0.0, 10.0).intersects(Rangef::new(5.0, 15.0)));
assert!(Rangef::new(0.0, 10.0).intersects(Rangef::new(5.0, 6.0)));
assert!(Rangef::new(0.0, 10.0).intersects(Rangef::new(10.0, 20.0)));
assert!(!Rangef::new(0.0, 10.0).intersects(Rangef::new(20.0, 30.0)));``````
