-\* **Edge Cases Tested**: Indicates whether the ufunc has parametrized tests that compare QuadPrecision results against `float` and `np.float64` for edge cases including:
-
-- Special values: `0.0`, `-0.0`, `inf`, `-inf`, `nan`, `-nan`
-- For trigonometric functions: Critical points like `0`, `π/2`, `π`, `3π/2`, `2π`, values in `[0, 2π]`
-- For logarithmic functions: Values near `0`, `1`, large values
-- For exponential functions: Large positive/negative values, values near `0`
-
-**Testing Status:**
-
-- ✅ = Comprehensive edge case tests exist in `test_quaddtype.py` with parametrized tests against float64
-- 🟡 = Good basic testing exists but missing some edge cases (specific missing tests noted in italics)
-- ❌ = Ufunc is implemented but lacks systematic testing (required tests noted in italics)
-- (blank) = Ufunc not yet implemented (implementation needed first)
