Exception for Random Jason Timeout Test 012

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

• could not determine a ground truth for program body

  1. a = 8.776596381696226e+279

Math

\[\cos^{-1} \left({\left(\left(\cosh a\right) \bmod \left(a \cdot a\right)\right)}^{\left(\mathsf{log1p}\left(a\right)\right)}\right)\]

C

double f(double a) {
        double r1426 = a;
        double r1427 = cosh(r1426);
        double r1428 = r1426 * r1426;
        double r1429 = fmod(r1427, r1428);
        double r1430 = log1p(r1426);
        double r1431 = pow(r1429, r1430);
        double r1432 = acos(r1431);
        return r1432;
}
