Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.(Inherited from Scalar.)
Gets an evaluator that can be used to find the product of the scalars, including derivatives up to the requested order.
In an effort to avoid excessively large call stacks the resulting evaluator will recursively collapse any child scalar that is also a ScalarProduct into the parent evaluator. For example, (a * (b * c)) will become (a * b * c).
