Function Names
powDescription
Calculates the x (base value) ^ y (power exponent).
Vectorization: This function supports vectorization in the 1st and 2nd function parameters.
Instead of providing a single value, you can provide a set or even a nested set which contain multiple values.
The function will then process every value and its return value contains a corresponding set containing all results.
Call as: function
