Hi Ray,

Thanks for your report. If you have a correction you can upload it to the bug tracker or just post it to this list.

I don't know much about these functions but maybe someone else on the list can check it. Based on that code snippet, it looks like it starts off with a finite sum approximation to the true value, and then refines that approximation with an infinite sum? It seems to pass in the finite sum value to the infinite sum routine.

But you're saying under certain argument conditions, its not necessary to refine the initial approximation with the infinite sum?

I have added an analysis to the bug report.   Somebody needs to double
check it; I usually get things a little wrong the first time through.
If it should happen that my suggestion is valid; how and where do I
submit a correction?
