Function spinoso_math::atanh

source · [−]

pub fn atanh(value: f64) -> Result<f64, DomainError>

Expand description

Computes the inverse hyperbolic tangent of the given value.

Domain: (-1, 1)

Codomain: (-INFINITY, INFINITY)

Examples

use spinoso_math as math;
assert_eq!(math::atanh(1.0), Ok(f64::INFINITY));
assert!(math::atanh(100.0).is_err());

assert!(matches!(math::atanh(f64::NAN), Ok(result) if result.is_nan()));

Errors

If the result of computing the inverse hyperbolic tangent is NAN a domain error is returned.
