OK, I’ll fix it and double check the other tests against the c reference.

Are changes to numbers going under Jira tickets?
It looks like it needs an update to checkstyle, PMD, spotbugs, the
commons-parent and travis.
Checkstyle config from commons-rng finds:

The mass of errors is white space style in the test classes. Without the test

Also looking at Complex it would benefit from:
public Complex subtractFrom(double minuend) {
return new Complex(minuend - real, imaginary);
}
This would avoid:
Complex a = …;
double b = …;
Complex c = Complex.ofCartesian(b - a.real(), a.imag());
Complex d = Complex.ofReal(b).subtract(a).conj();
With
Complex a = …;
double b = …;
Complex c = a.subtractFrom(b);
