pub fn asin(value: f64) -> Result<f64, DomainError>Expand description
Computes the arcsine of the given value. Returns results in the range
(-PI/2..=PI/2).
Domain: [-1, -1]
Codomain: [-PI/2, PI/2]
§Examples
use spinoso_math as math;
assert_eq!(math::asin(1.0), Ok(PI / 2.0));
assert!(math::asin(100.0).is_err());
assert!(matches!(math::asin(f64::NAN), Ok(result) if result.is_nan()));§Errors
If the result of computing the arcsine is NAN, a domain error is
returned.
