Document

Solves the quadratic whose coefficients are in the eqn array and places the non-complex roots into the res array, returning the number of roots.

Usage

From source file:Quadradic.java

protected int findRoots(double y, double[] roots) {
    double[] eqn = { p1.y - y, 2 * (p2.y - p1.y), p1.y - 2 * p2.y + p3.y };
    return QuadCurve2D.solveQuadratic(eqn, roots);
    // return solveQuad(eqn[2], eqn[1], eqn[0], roots);
}
