@Override
public void load() {
  add(new CustomFunction.Builder(true, "log", Arrays.asList("base", "x"), "ln(x)/ln(base)"));
  add(new CustomFunction.Builder(true, "√3", Arrays.asList("x"), "x^(1/3)"));
  add(new CustomFunction.Builder(true, "√4", Arrays.asList("x"), "x^(1/4)"));
  add(new CustomFunction.Builder(true, "√n", Arrays.asList("x", "n"), "x^(1/n)"));
  add(new CustomFunction.Builder(true, "re", Arrays.asList("x"), "(x+conjugate(x))/2"));
  add(new CustomFunction.Builder(true, "im", Arrays.asList("x"), "(x-conjugate(x))/(2*i)"));
  super.load();
}

@Nonnull
@Override
public CustomFunction create() {
  final CustomFunction customFunction = new CustomFunction(name, parameterNames, prepareContent(content), description);
  customFunction.setSystem(system);
  if (id != null) {
    customFunction.setId(id);
  }
  return customFunction;
}

  @Nonnull
  @Override

    final AFunction function = nestedBuilder.create();
    return new CustomFunction.Builder(function).create();
