Exception for Linear.Projection:inversePerspective from linear-1.19.1.3, C

Math

\[\frac{x + y}{\left(x \cdot 2\right) \cdot y}\]

C

double f(double x, double y) {
        double r8595 = x;
        double r8596 = y;
        double r8597 = r8595 + r8596;
        double r8598 = 2.0;
        double r8599 = r8595 * r8598;
        double r8600 = r8599 * r8596;
        double r8601 = r8597 / r8600;
        return r8601;
}
