470-473: LGTM: Good addition for handling root == 0 case.The new condition to handle the case when
rootis zero is a good improvement. It correctly returnsLegacyOneDec()for this special case.Consider updating the comment to be more precise:
-- Return 1 as root 0 of any number is considered 1. ++ Return 1 as the 0th root of any number is undefined, but 1 is a sensible default.

470-504: Summary: Improvements to ApproxRoot functionThe changes to the
ApproxRootfunction are well-implemented and improve both functionality and readability:
- Addition of a special case for
root == 0.- Simplification of the loop condition.
- Updated comments for better clarity.
These modifications enhance the function without altering its core behavior. The changes are localized and shouldn't negatively impact other parts of the codebase.
488-504: Approve simplification of loop condition.The simplification of the loop condition improves readability while maintaining the same functionality. The new condition
delta.Abs().LTE(smallestDec)is a clear and concise way to determine when to break the loop.Let's verify if this change affects other parts of the codebase:
✅ Verification successful
Approve the simplification of the loop condition.
The change is localized to the
ApproxRootfunction withinmath/dec.goand is covered by existing tests inmath/dec_test.go. No other parts of the codebase are affected by this modification.🏁 Scripts executed
The following scripts were executed for the analysis:

The changes look good! More readable and efficient code. 👍
It would be great if you could add a test scenario to for root=0 to the test-suite. This would help with regression.
