pub fn sqrt(value: f64) -> Result<f64, DomainError>
Expand description
Returns the non-negative square root of the given value.
Domain: [0, INFINITY)
Codomain: [0, INFINITY)
§Examples
use spinoso_math as math;
assert_eq!(math::sqrt(0.0), Ok(0.0));
assert_eq!(math::sqrt(1.0), Ok(1.0));
assert_eq!(math::sqrt(9.0), Ok(3.0));
assert!(math::sqrt(-9.0).is_err());
assert!(matches!(math::sqrt(f64::NAN), Ok(result) if result.is_nan()));
§Errors
If the result of computing the square root is NAN
, a domain error is
returned.
