Exception for From Rump in a 1983 paper

\[x = 10864 \land y = 18817\]

Math

\[\left(9 \cdot {x}^{4} - {y}^{4}\right) + 2 \cdot \left(y \cdot y\right)\]

C

double f(double x, double y) {
        double r8648 = 9.0;
        double r8649 = x;
        double r8650 = 4.0;
        double r8651 = pow(r8649, r8650);
        double r8652 = r8648 * r8651;
        double r8653 = y;
        double r8654 = pow(r8653, r8650);
        double r8655 = r8652 - r8654;
        double r8656 = 2.0;
        double r8657 = r8653 * r8653;
        double r8658 = r8656 * r8657;
        double r8659 = r8655 + r8658;
        return r8659;
