Exception for a parameter of renormalized beta distribution

\[0.0 \lt m \land 0.0 \lt v \land v \lt 0.25\]

Math

\[\left(\frac{m \cdot \left(1 - m\right)}{v} - 1\right) \cdot m\]

C

double f(double m, double v) {
        double r8097 = m;
        double r8098 = 1.0;
        double r8099 = r8098 - r8097;
        double r8100 = r8097 * r8099;
        double r8101 = v;
        double r8102 = r8100 / r8101;
        double r8103 = r8102 - r8098;
        double r8104 = r8103 * r8097;
        return r8104;
}
