Describe your changes

test(deep_causality_num): Added atan impl to RealField and default impl.

Fixed typo

Issue ticket number and link

Code checklist before requesting a review

• I have signed the DCO?
• All tests are passing when running make test?
• No errors or security vulnerabilities are reported by make check?

For details on make, please see BUILD.md

Note: The CI runs all of the above and fixing things before they hit CI speeds
up the review and merge process. Thank you.

PR Code Suggestions ✨

Latest suggestions up to 425007f

Category	Suggestion	Impact
Incremental [*]	Make doctest numerically robust Improve the atan doctest by replacing the atan(tan(1)) check with the more stable and direct identity atan(1) = pi/4. deep_causality_num/src/algebra/field_real.rs [157-166] /// ``` /// use deep_causality_num::RealField; /// -/// let f = 1.0; +/// let x = 1.0f64; /// -/// // atan(tan(1)) -/// let abs_difference = (f.tan().atan() - 1.0).abs(); +/// // atan(1) = pi/4 (principal value) +/// let abs_difference = (x.atan() - (f64::pi() / 4.0)).abs(); /// /// assert!(abs_difference < 1e-10); /// ``` Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies that the doctest can be improved by using a more direct and numerically stable identity, which enhances the test's clarity and robustness.	Low
General	Inline the f64 wrapper Add the #[inline] attribute to the f64 implementation of atan for consistency with other similar functions in the file. deep_causality_num/src/algebra/field_real.rs [602-604] +#[inline] fn atan(self) -> Self { f64::atan(self) } Apply / Chat Suggestion importance[1-10]: 5 __ Why: The suggestion correctly points out an inconsistency with other function implementations in the file, and applying it improves code consistency and potentially performance.

Suggestions up to commit 425007f

Category	Suggestion	Impact
Incremental [*]	Fix incorrect arctangent call Replace the invalid associated function call f32::atan(self) with the correct inherent method call self.atan() to prevent a compilation error. deep_causality_num/src/algebra/field_real.rs [418-421] #[inline] fn atan(self) -> Self { - f32::atan(self) + self.atan() } Suggestion importance[1-10]: 10 __ Why: The suggestion correctly identifies that f32::atan(self) is invalid syntax which will cause a compilation error and provides the correct fix self.atan().	High
Possible issue	Make doc-test call trait method Update the atan doc-test to use Universal Function Call Syntax (UFCS), ensuring it explicitly tests the RealField trait method rather than the inherent f64 method. deep_causality_num/src/algebra/field_real.rs [157-167] /// ``` /// use deep_causality_num::RealField; /// -/// let f = 1.0; +/// let f: f64 = 1.0; /// /// // atan(tan(1)) -/// let abs_difference = (f.tan().atan() - 1.0).abs(); +/// let abs_difference = (<f64 as RealField>::atan(f.tan()) - 1.0).abs(); /// /// assert!(abs_difference < 1e-10); /// ``` fn atan(self) -> Self; Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies that the doc-test for atan does not test the trait method as intended, and the proposed fix using Universal Function Call Syntax (UFCS) ensures the test correctly validates the trait implementation.	Low
General	Inline the floating-point implementation Add the #[inline] attribute to the f64 implementation of atan for consistency with other methods and potential performance benefits. deep_causality_num/src/algebra/field_real.rs [602-604] +#[inline] fn atan(self) -> Self { f64::atan(self) } Suggestion importance[1-10]: 5 __ Why: The suggestion correctly recommends adding #[inline] to the atan implementation for f64, which makes it consistent with other method implementations in the file and is a good practice for performance.	Low

✅ Suggestions up to commit f29aa7d

Category	Suggestion	Impact
General	✅ Add missing inline attribute for performance Suggestion Impact: The commit adds the #[inline] attribute directly above the f32 atan method, matching the suggestion. code diff: + #[inline] fn atan(self) -> Self { f32::atan(self) Add the #[inline] attribute to the atan implementation for f32 for consistency and performance. deep_causality_num/src/algebra/field_real.rs [418-420] +#[inline] fn atan(self) -> Self { f32::atan(self) } [Suggestion processed] Suggestion importance[1-10]: 5 __ Why: The suggestion correctly points out the missing #[inline] attribute, which is consistently used for similar wrapper functions in the file, thus improving consistency and potentially performance.	Low
	✅ Add inline to DoubleFloat atan Suggestion Impact: The commit added #[inline] to the DoubleFloat atan() wrapper method (and repositioned the method within the impl), matching the suggested change. code diff: #[inline] + fn atan(self) -> Self { + <Self as Float>::atan(self) + } + + #[inline] fn atan2(self, other: Self) -> Self { <Self as Float>::atan2(self, other) } @@ -211,9 +216,5 @@ fn epsilon() -> Self { Self::EPSILON } - - fn atan(self) -> Self { - <Self as Float>::atan(self) - } -} - +} Add the #[inline] attribute to the atan implementation for DoubleFloat for consistency and performance. deep_causality_num/src/float_double/traits_algebra.rs [215-217] +#[inline] fn atan(self) -> Self { <Self as Float>::atan(self) } [Suggestion processed] Suggestion importance[1-10]: 5 __ Why: The suggestion correctly points out the missing #[inline] attribute, which is consistently used for similar wrapper functions in the file, thus improving consistency and potentially performance.	Low
	✅ Fix doc import to RealField Suggestion Impact: The doc-test import line was changed from `use deep_causality_num::Float;` to `use deep_causality_num::RealField;` as suggested.
