Implementations

impl<T> Radians<T>

where T: Float + FloatConst,

pub fn abs(self) -> Radians<T>

The absolute value of the angle.

pub fn half(self) -> Radians<T>

Half of the angle.

pub fn opposite(self) -> Radians<T>

The opposite angle on the circle, i.e. +/- PI.

pub fn clamp(self, max_value: Radians<T>) -> Radians<T>

Clamp value into the range: 0.0..=max_value.

Examples

use angle_sc::Radians;

let value = Radians(-f64::EPSILON);
assert_eq!(Radians(0.0), value.clamp(Radians(1.0)));
let value = Radians(0.0);

let value = Radians(1.0);
assert_eq!(Radians(1.0), value.clamp(Radians(1.0)));
let value = Radians(1.0 + f64::EPSILON);
assert_eq!(Radians(1.0), value.clamp(Radians(1.0)));

Trait Implementations

impl<T> Add for Radians<T>

let angle_120 = Radians(2.0 * core::f64::consts::FRAC_PI_3);
let result = angle_120 + angle_120;
assert!(is_within_tolerance(-2.0 * core::f64::consts::FRAC_PI_3, result.0,  4.0 * f64::EPSILON));
