OK, so I will code some functions and propose them for addition to
what we have here.
I'll start with the very simplest ones (log1p, expm1, cosm1) as I
have a fairly clear idea (I hope ;-) ) of what to expect from them and
how to code them.
Then perhaps cbrt and pow (though I would like to know the precise
C99 wording to see what people expect from them, say as to the range of
the integer exponent for pow or the behaviour of cbrt on negative reals
(that ought to be obvious, but then again...)).
Things will become really interesting with beta, erf and erfc.
At that stage, I guess time will be ripe to discuss in more
details what we want effectively out of the list of proposed functions
and proceed, with these examples in hand.
I will attempt to code for accuracy first, where its importance is
expected (say around 0 for expm1), with a fall-back on standard library
