pub fn acos(value: f64) -> Result<f64, DomainError>Expand description
Computes the arccosine of the given value. Returns results in the range
(0..=PI).
Domain: [-1, 1]
Codomain: [0, PI]
§Examples
use spinoso_math as math;
assert_eq!(math::acos(0.0), Ok(PI / 2.0));
assert!(math::acos(100.0).is_err());
assert!(matches!(math::acos(f64::NAN), Ok(result) if result.is_nan()));§Errors
If the result of computing the arccosine is NAN, a domain error is
returned.
