Exception for Hyperbolic arcsine

Math

\[\log \left(x + \sqrt{x \cdot x + 1}\right)\]

C

double f(double x) {
        double r8249 = x;
        double r8250 = r8249 * r8249;
        double r8251 = 1.0;
        double r8252 = r8250 + r8251;
        double r8253 = sqrt(r8252);
        double r8254 = r8249 + r8253;
        double r8255 = log(r8254);
        return r8255;
}

(FPCore (x)
  :name "Hyperbolic arcsine"

  :herbie-target
  (if (< x 0.0) (log (/ -1.0 (- x (sqrt (+ (* x x) 1.0))))) (log (+ x (sqrt (+ (* x x) 1.0)))))

  (log (+ x (sqrt (+ (* x x) 1.0)))))
