From source file:geogebra.kernel.statistics.AlgoInverseExponential.java

protected final void compute() {

    if (input[0].isDefined() && input[1].isDefined()) {
        double param = a.getDouble();
        double val = b.getDouble();
        try {/*from   w  w  w . j  ava  2 s.c  o m*/
            ExponentialDistribution dist = getExponentialDistribution(param);
            num.setValue(dist.inverseCumulativeProbability(val)); // P(T <= val)

        } catch (Exception e) {
            num.setUndefined();
