Known Issues, and TODO List

Predominantly this is a TODO list, or a list of possible future enhancements. Items labled "High Priority" effect the proper functioning of the component, and should be fixed as soon as possible. Items labled "Medium Priority" are desirable enhancements, often pertaining to the performance of the component, but do not effect it's accuracy or functionality. Items labled "Low Priority" should probably be investigated at some point. Such classifications are obviously highly subjective.

If you don't see a component listed here, then we don't have any known issues with it.

tgamma
Incomplete Beta
Inverse Gamma
Polynomials
Elliptic Integrals
Owen's T Function

There is a problem area at arbitrary precision when a is very close to 1. However, note that the value for T(h, 1) is well known and easy to compute, and if we replaced the ak terms in series T1, T2 or T4 by (ak - 1) then we would have the difference between T(h, a) and T(h, 1). Unfortunately this doesn't improve the convergence of those series in that area. It certainly looks as though a new series in terms of (1-a)k is both possible and desirable in this area, but it remains elusive at present.

Jocobi elliptic functions

These are useful in engineering applications - we have had a request to add these.
