Boost :

I have been exploring the use of Stephen Moshier's Cephes Library in C
(which the author has agreed to make available under the Boost license)
to provide an implmentation of many of these functions,

AND the other missing, and in many cases MUCH more important IMHO, math
'special' functions,
mainly requiring the Incomplete beta function,
as I proposed

but which was rejected as 'too difficult' - for which I suspect means 'too

Many of the functions in TR1 appear to be present in Cephes and require
to produce AN implementation in C++ (almost certainly not as good as
but still functional and Standard compliant - since no accuracy is

So I am slightly optimistic that we might be able to produce a Boost version
that provides BOTH TR1 and the additional proposals for TR2.

| Correct.
