Exception for Random Jason Timeout Test 015

• Falling back on racket egraph because egg-herbie package not installed

• could not determine a ground truth for program body

  1. a = 4.773292077298795e+235
  2. b = 2.4612524637435313e-181

Math

\[\sin \left({\left(\sqrt{\tan^{-1}_* \frac{b}{b}}\right)}^{\left(b - a\right)}\right)\]

C

double f(double a, double b) {
        double r447 = b;
        double r448 = atan2(r447, r447);
        double r449 = sqrt(r448);
        double r450 = a;
        double r451 = r447 - r450;
        double r452 = pow(r449, r451);
        double r453 = sin(r452);
        return r453;
}
