Expand description

The roots of a real quadratic a·x² + b·x + c = 0.

Variants§

§

TwoReal(f64, f64)

Two distinct real roots, ascending.

§

DoubleReal(f64)

One repeated real root (discriminant ≈ 0).

§

ComplexPair

A complex conjugate pair re ± im·i (im > 0).

Fields

§re: f64

§im: f64

§

Linear(f64)

Degenerate leading coefficient (a ≈ 0): the single linear root of b·x + c = 0.
