Exception for math.log/1 on complex, real part

Math

\[\log \left(\sqrt{re \cdot re + im \cdot im}\right)\]

C

double f(double re, double im) {
        double r8335 = re;
        double r8336 = r8335 * r8335;
        double r8337 = im;
        double r8338 = r8337 * r8337;
        double r8339 = r8336 + r8338;

        double r8341 = log(r8340);
        return r8341;
}
