Exception for b parameter of renormalized beta distribution

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

Math

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

C

double f(double m, double v) {
        double r7979 = m;
        double r7980 = 1.0;
        double r7981 = r7980 - r7979;
        double r7982 = r7979 * r7981;
        double r7983 = v;
        double r7984 = r7982 / r7983;
        double r7985 = r7984 - r7980;
        double r7986 = r7985 * r7981;
        return r7986;
}
