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 r8945 = x;
        double r8946 = y;
        double r8947 = r8945 + r8946;
        double r8948 = 2.0;
        double r8949 = r8945 * r8948;
        double r8950 = r8949 * r8946;
        double r8951 = r8947 / r8950;
        return r8951;
}
