Exception for Bouland and Aaronson, Equation (26)

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

Math

\[\left({\left(a \cdot a + b \cdot b\right)}^{2} + 4 \cdot \left(b \cdot b\right)\right) - 1\]

C

double f(double a, double b) {
        double r97599 = a;
        double r97600 = r97599 * r97599;
        double r97601 = b;
        double r97602 = r97601 * r97601;
        double r97603 = r97600 + r97602;
        double r97604 = 2.0;
        double r97605 = pow(r97603, r97604);
        double r97606 = 4.0;
        double r97607 = r97606 * r97602;
        double r97608 = r97605 + r97607;
        double r97609 = 1.0;
        double r97610 = r97608 - r97609;
        return r97610;
}

(FPCore (a b)
  :name "Bouland and Aaronson, Equation (26)"
  :precision binary64
  (- (+ (pow (+ (* a a) (* b b)) 2) (* 4 (* b b))) 1))
