-# Complex Numbers (`lyng.complex`)
-
-`lyng.complex` adds a pure-Lyng `Complex` type backed by `Real` components.
-
-Import it when you want ordinary complex arithmetic:
-
-```lyng
-import lyng.complex
-```
-
-## Construction
-
-Use any of these:
-
-```lyng
-import lyng.complex
-
-val a = Complex(1.0, 2.0)
-val b = complex(1.0, 2.0)
-val c = 2.i
-val d = 3.re
-
-assertEquals(Complex(1.0, 2.0), 1 + 2.i)
-```
-
-Convenience extensions:
-
-- `Int.re`, `Real.re`: embed a real value into the complex plane
-- `Int.i`, `Real.i`: create a pure imaginary value
-- `cis(angle)`: shorthand for `cos(angle) + i sin(angle)`
-
-## Core Operations
-
-`Complex` supports:
-
-- `+`
-- `-`
-- `*`
-- `/`
-- unary `-`
-- `conjugate`
-- `magnitude`
-- `phase`
-
-Mixed arithmetic with `Int` and `Real` is enabled through `lyng.operators`, so both sides work naturally:
-
-```lyng
-import lyng.complex
-
-assertEquals(Complex(1.0, 2.0), 1 + 2.i)
-assertEquals(Complex(1.5, 2.0), 1.5 + 2.i)
-assertEquals(Complex(2.0, 2.0), 2.i + 2)
-```
-
-Mixed equality with built-in numeric types is intentionally not promised yet. Keep equality checks in the `Complex` domain for now.
-
-## Transcendental Functions
-
-For now, use member-style calls:
-
-```lyng
-import lyng.complex
-
-val z = 1 + π.i
-val w = z.exp()
-val s = z.sin()
-val r = z.sqrt()
-```
-
-This is deliberate. Lyng already has built-in top-level real-valued functions such as `exp(x)` and `sin(x)`, and imported modules do not currently replace those root bindings. So plain `exp(z)` is not yet the right extension mechanism for complex math.
-
-## Design Scope
-
-This module intentionally uses `Complex` with `Real` parts, not `Complex<T>`.
-
-Reasons:
-
-- the existing math runtime is `Real`-centric
-- the operator interop registry works with concrete runtime classes
-- transcendental functions (`exp`, `sin`, `ln`, `sqrt`) are defined over the `Real` math backend here
-
-If Lyng later gets a more general numeric-trait or callable-overload registry, a generic algebraic `Complex<T>` can be revisited on firmer ground.

-Complex number backed by `Real` components.

-This module intentionally keeps the storage model simple:
-- `re`: real part
-- `im`: imaginary part
-
-The algebra is implemented in pure Lyng and interoperates with `Int` and `Real`
-through `lyng.operators`, so expressions like `1 + 2.i` and `0.5 * (1 + 2.i)` work.
-
-For transcendental functions, use the member-style API for now:
-- `z.exp()`
-- `z.ln()`
-- `z.sin()`
-- `z.cos()`
-- `z.tan()`
-- `z.sqrt()`
-
-This avoids collisions with the built-in real-valued top-level math functions
-such as `exp(x)` and `sin(x)`.
