[Don Clugston]

Like any good engineer, MathExtra has the goal of doing itself out of a job.
Progress towards this goal will be reported in this thread.

It's possible that this project will never make an official release; instead, releases will be made through Phobos /Ares.

MathExtra's raison d'etre at present is (a) as insurance for D in case I'm hit by truck, or otherwise fail to complete the project; and (b) a repository for functions which are too obscure for inclusion in a general-purpose library.
============================

Many functions accepted into DMD 0.143.

* asinh, acosh, atanh, -- real args only
* conj -- ireal, creal
* abs -- for everything
+ isPosZero, isNegZero

All those functions are now removed from MathExtra.

Here are some comments from Walter (digitalmars.com digitalmars.D.announce:2508) which are relevant to the future of MathExtra:

Back when I worked at Boeing, I wrote numerical analysis programs in
FORTRAN. It's what made me interested in having good floating point support.
Interestingly, about all this stuff was proposed for C at one time around
1990, but it fizzled for reasons I don't understand.

I agree.
