Exception for Random Jason Timeout Test 003

• 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 r1784 = b;
        double r1785 = atan2(r1784, r1784);
        double r1786 = sqrt(r1785);
        double r1787 = a;
        double r1788 = r1784 - r1787;
        double r1789 = pow(r1786, r1788);
        double r1790 = sin(r1789);
        return r1790;
}
