Previous opinions were in favour of a larger set of constants,
and there was considerable discussion about a set of names which
were finally agreed to be reasonably consistent.

Are you forgetting the very important need that the constants
mesh with the Boost interval library?
For these I think you need pi_div_3, for example,
to provide the upper and lower interval values.
(These in turn depend on the floating-point format).

What about the complex case, for which an example is provided
by Michael Kennistons scheme?
