Division: TGraph and TGraphErrors

I have two objects of type TGraph, for example GrA and GrB and I wish to make a division GrC = GrA/GrB. Do we a function for this operation which I may have overlooked?

…or do for-loop to get the values at each point , GetPoint(), do the division then set the points?

In the case of TGraphErrors, I ask the same question. How about its treatment of errors?

Many thanks.
